I really wish I had been able to finish that project yesterday.
I'm sorry to hear that you couldn't finish it! What couldn't you finish?
It was a project for work. I was going to get a bonus if I met yesterday's deadline. I could really kick myself about not being able to finish on time.
Hey you are being too hard on yourself. I'm sure your boss would prefer it done well and not rushed. 
Yeah, maybe so, but I really could have used that bonus.
