regret

She left without even saying goodbye to us.

She was so absorbed in listening to the Beatles that she missed her date with him.

I shouldn't have logged out.

He hopes the unpleasant memories will fade away.

You should have rejected such an unfair proposal.

I was playing ball in my room this morning and ended up breaking the one I'd been using until now.

What I regret now is, rather, the time I wasted.

Truth be told, I'd be lying if I said I didn't regret deciding on the spot.

She bit her lip with regret, wishing she hadn't said those things that got on her mother-in-law's nerves.

I went and said something I shouldn't have said.

Ugh... I was young, sure, but what a stupid rookie mistake.

I shouldn't have gone overboard.

If only I could get back the time I wasted.

My father should have had surgery for cancer.

If only my father had lived longer.

She regretted not having listened to his advice.

She was completely taken in by his gentlemanly facade.

When she got lost, she thought she should have listened to his advice.

She gave up the plan against her own wishes.

She is ashamed of what she has done.

She reflected on what she had done.

She accidentally broke the vase.

She admitted she had made a mistake.

She regretted not pursuing a career in music.

She really shouldn't have done such a thing.

She didn't even need to do that work.

She didn't have to come to the meeting.

She didn't have to pay that money.

She was brooding over the unhappy days she had spent there.

She gave me a wonderful watch, but I went and lost it.
