Aren't

"Why aren't you going?" "Because I don't want to."

These things aren't mine!

If you don't understand something, it's because you aren't aware of its context.

Aren't you ashamed to talk like that?

Why aren't you coming with us?

You are tired, aren't you?

You work too hard these days. Aren't you tired?

You are really full of curiosity, aren't you?

You may think those shoes are in fashion, but they aren't.

You aren't a spy, are you?

I’m a nasty-tempered dog if any one tries to take my bone away; aren’t I, my sons?

Aren’t I supposed to tell you how I feel?
