Hi expert teachers,

Why don’t people care for others? They’re alwzys in themselves. Correct?

Many thanks.

Hi, I’m not sure. I find it is strange.
I’d say :
Why don’t people care for others? They always care about themselves.
(I suppose you’re aware of “alwzys” is a typo)

3

I also find it strange.
Perhaps you are thinking of the (very informal) phrase ‘they are always up themselves’

4

Thank you very much, BN.

They are always up themselves. It means they think of their problems only, right?

5

they think they are better or more important than others.
