You shouldn't have done it

The interview didn't go too well

This food is burnt.

I think that dress looks awful on her.

My girlfriend left me.

I should have prepared more thoroughly.

She shouldn't have ordered so much.

I shouldn't have gone to bed so late last night.

You shouldn't have left it in the oven so long.

We should have chosen an action one

I should have put on thicker socks.
