I'm really sorry.
I want to apologize for how badly I treated you. Of course, you'll probably never read this, but I might as well write it in some sort of vaguely guilty hopeful way.
I know it was a long time ago, but I'm sorry about that date. It was really brave of you to ask me. I'm sorry I didn't want to dance, and that I wanted to go home early. I was just selfish. All I was doing was focusing on me, and how I felt. I didn't stop to think how I might be making you feel.
So, I'm sorry.
Because now I know exactly how that feels.
I hope you can forgive me someday.
