I cannot imagine a world without forget about something. Sometimes, we make something wrong, and I use to apologize too many times. I forgive everybody, I belive in second chances. And I forget sometimes who did wrong to me. It's that the thing about being happy? Forgetting? Then, I'll be happy.
Then, go out and give a second chance. Or, if you can't, only forget. You won't get hurt.
P.D: Don't forget, Demi Lovato. Yeah, I know it's not what I was talking about, but I like it very much today ^^
