"no, I shouldn't have done this!"

Today I did 3 things which I shouldn't do.
1. I have stolen a menu from a restaurant. (it's not my idea, but they put it in my bag. That's why I'm guilty)
2. I copied answer for the exercise that teacher want us to do. I'm feeling guilty right now.
3. I borrowed a pen from my friend, an I put it at somewhere else, which means I have lost it. Feeling guilty again.

To make me feel better, I will go and buy a new pen for her. Please remind me. =.=
