I stole some candy from the store yesterday and now I can't sleep at night.
Hmmm, maybe that's because you ate it and you've got a sugar rush. I wouldn't worry! That usually fades in a couple hours. 
I hope so. I've never stolen anything in my life. I feel somewhat bad.
Eh, it's okay. Don't beat yourself up about it. It's truly a victimless crime. There are much, much worse things you could have done, I promise.
