An English question?

Question

Hi everyone , I 'm studying English . I want to know when you want to say a greeting to a person who has had a busy day or hard work or he is very tired , What do say to him/her ?
In Persian we say : Don't be tired . But i know in English don't say it .
Some one said me we can say " be fresh " but i want to know some kind of other greeting .
Thanks .

For example , when a class comes to end , What could Students say to the teacher that it means " Don't be tired " ?

Answer 1

You look as though you could do with a good rest.

The typical thing to say if you are English is "You look as though you could do with a cup of tea!" But only if you are ready to offer it!

You could say to your teacher: "Enjoy the rest of the day/evening!"

Answer 2

"Be fresh" sounds wrong to me.
You could say "take it easy" but not as a greeting. "Rough day?" would work as a greeting or "You look like hell" but it's not very nice. I can't think of a really nice way to tell someone they look tired, but there are ways to act concerned. "Are you ok?" for example.

Answer 3

There isn't a particular one, I don't think but if I was saying hello to someone who was tired I might say Hi, had a hard day? or. . . . Hi, you look tired. Are you ok?

Answer 4

there's nothing specific that I know of, but, when you say goodbye, many people say "take care", and that's probably the closest to your "be fresh" persian version...

I'll check up later to see what other people respond,

Good luck!

Answer 5

well, there really isnt anything you actually say to that except, hey whats up? you look tired.....you ok?

Answer 6

You can say "hello" you look exhausted. Is everything okay?
