Answer 2

They probably wouldn't get the message, so just have fun with them.

Suggest a list of things they should always have checked on their car, like making sure their oil pan is well waxed;

If you work in a one-story building with this person, ask them to please change the toilet paper in the upstairs bathroom.. see if they grab the toilet paper rolls

Ask them if they know where the keys to the parking lot are, or if we're out of bulbs for the skylights...

I don't think they will ever catch on, so have fun with it.....

Answer 5

A father put his three year old daughter to bed, told her a story, and listened to her prayers which she ended by saying “God bless mommy, God bless daddy, and God bless grandma and good-bye grandpa.” The farther ask, “Why did you say good-bye grandpa?” The little girl said “I don’t know daddy, It just seemed like the thing to do.” The next day grandpa died. The father thought it was a strange coincidence. A few months later the father put the girl to bad and listened to her prayers, which went like this: “God bless mommy, God bless daddy and good-bye grandma.” The next day grandma died. Oh my gosh, thought the father, this kid is in contact with the other side. Several weeks later when the girl was going to bed the dad heard her say, “God bless mommy and good-bye daddy.” He practically went into shock. He couldn’t sleep all night and, got up at the crack of dawn to go to his office. He was Nervous as a cat all day, had lunch sent in and watched the clock. He figured if he could get by until midnight he would be okay. He felt safe in the office, so instead of going home at the end of the day he stayed there, drinking coffee, looking at his watch and jumping at every sound. Finally midnight arrived, he breathed a sigh of relief and went home. When he got home his wife said “ I’ve never seen you work so late, what’s the matter?” He said “I don’t want to talk about it, I’ve just spent the worst day of my life.” She said “You think you had a bad day, you’ll never believe what happened to me. This morning the milkman dropped dead on our porch.”
