Dear dad, you're pretty chill most of the time. I appreciate all that you do for me and all the hours you spend working to provide from us... but you've gotta understand a few things. One, I can't stand hanging around you when you're drunk, which is all the time. I really wish you'd quit. Two, there are some things I'm sensitive about, like my education and my future, and snide comments about them really piss me off. Three, I know you think calling me "fatass" is cute and a funny nickname, and you don't mean anything by it, but it does hurt my feelings, even if I play along with it like I have for the past 8 or so years.
Dear past me, I'm sorry I've let you down. I know you thought I'd be married and have a job and a house and a really cool basset hound dog by now. I envy how outgoing and optimistic you were, I wish I didn't become so bitter and withdrawn. I wish I knew what happened to our outlook on life. But I'd like to think you'd be at least just a little bit proud of the fact that I never quit loving those same cartoons we loved so much when I was you and the fact that we kept our grades up all the way through school and graduated with honors. All in all, past self, I miss being you.
