I overdid it.

Did you ask her out? No, I was too nervous. I was too uptight. 我太紧张了.

I wish I had studied harder. 我要是再用功点就好了*..wish..had done要是..就好了 I regret not studying harder. I should have studied harder.

I should have asked him.我要再问他一下就好了. Why didn't you? I wish I had asked him.

It would have been better to have asked him. Did you remember to tell her? Sorry,

it slipped my mind.不小心给忘了 I just forgot. I forgot all about it.
