I have changed
It's funny. You say I've changed. You say you don't like my attitude now.
I have changed. That what happens when people grow up. They change. It's also what happens when they get hurt. They have to learn to adapt.
As for my attitude, it's the exact same as the one you've been giving me for years now. So if you don't like it now, after only a few months, imagine how I feel.
