Question

I have written a story about a person living in the 22nd century after WW3 but it never meantions that in the story, i have to put it in, but were?

A fierce wind hit Lilith’s bare legs as she walked the empty beach, straining to go any further. She held a cloth bag in her right hand, the one she used for carrying food and other objects found along the beach. Her vision was clouded with fog, and she was afraid of getting lost. The beautiful scenery of harsh icy waves distracted Lilith from her work. Thoughts of confusion flowed through her brain like liquid, one after the other. She wondered why her people were so cruel to bring this horribly cold weather with their weapons of mass destruction leading to a nuclear winter.
Lilith secretly looked for artifacts, as a way of comfort. Living in an utterly heartless community made her feel lost and alone. Only new discoveries seemed to relieve her pain. Her nine-year-old sister, Ivy, didn’t fully understand the tragic things she had to live through. Ivy was the only family she had left.

As Lilith let out a deep sigh something caught her eye, a rusty tubular object swaying back and forth through the stiff waves. Being a curious girl she ran over, slipping on the frosted sand into the numbing waters. Her wet hands aimlessly waving around as she tried to get out. Lilith crawled backwards, away from the water. Reaching the edges she noticed the object sitting beside her. Lilith quickly picked it up with excitement. It was covered in thick rust and hurt her small hands as she tried to open it with the little energy she had. Failing to get the object open, her only idea was to bring it home were she could get Ivy to help her.

Lilith eagerly ran home, not worrying if she were to slip again. As she entered the small, snow covered shed that she called home her sister let out a faint scream. Lilith, being confused, widened her eyes and asked,“What?” Ivy being a shy person, even to her sister didn’t reply. She simply got up, walked over to Lilith and touched her cheek. Ivy showed Lilith her fingertips with drops of blood.
“I slipped...” Lilith mumbled, “ just don’t worry, I’m fine.” She then remembered the rusty object in her bag. She took out the container and placed it in Ivy’s hands, “I found it on the beach.” Ivy looked at it as if it weren’t there, “...fun” she said sarcastically. Lilith frowned, “Help me open it.” They both took one end and tugged. It opened with a back chilling sound of rust. Lilith sat on the floor admiring the three strange things inside. Ivy slowly but eventually joined her, pointing to a long black object, “what is that?” she asked.

“Let me show you, hold out your arm.” Cautiously Ivy did as her sister told her. Lilith drew a small and unusual looking flower on her sister’s arm, making her smile sweetly. “You know a long time ago children your age used to draw pictures with these, they even had whole buildings just for hanging up pictures!” Lilith’s voice grew louder with excitement but Ivy quickly lost interest and pointed to another object, a plastic bottle with pink liquid inside.
“It’s used for turning you hair a different color...you mustn’t show anyone though. People used to spend time changing their hair color, painting their faces and even painting their nails! We can never do that though because God wants us to look the way he made us.” Ivy showed no sign of worry.

Lilith picked up the last object, “The sky was once bright, like a flame...before the war that is. People used these to protect their eyes.” She placed them on Ivy’s face and yawned, “They’re called sunglasses...but really, all this excitement is tiring me out,” Lilith rubbed her eyes, “We must go to sleep.” Ivy simply nodded and ran to a little mat over in the corner. She covered herself with a worn blue blanket, lying there waiting for her sister to kiss her goodnight. Lilith gathered all the objects and put them on a small shelf along with other things she had found, staring at them for a moment in amazement...such simple things kept her going.

Answer 1

¢ Hi. I answered you other question:
If I were you, I would try not to make it too obvious of the year, so I think I would try to add in the date around the end of the story. You could say something about maybe an old newspaper she had in her collection- give it a date from when it was from (2118?) and then say like "a hundred years old" or something like that
Know what I mean?

Answer 2

Her nine-year-old sister, Ivy, didn’t fully understand the tragic things she had to live through in the 22nd century after WW3, Ivy was the only family she had left.

Thats where I would put it I think Good luck

Answer 3

I agree there is no need to explicitly mention the war in the story although you should continue to write as if this was after the war.
It will interest readers to try and imagine the background against which the story takes place. If you tell them it's after the war they will probably say to themselves 'Oh I see" and move on to something else.

Answer 4

I think we get the idea, especially at the end. I think your story is fine the way it is.
