Why would i do this to myself?

Hey, listen, you're SIXTEEN ! Not 36. I know you think you know everything there is to know, but trust me, you don't. Look, you did a fine job of figuring out most of your problems in your question. Learn from your mistakes. It's pretty much that easy. Also, when you see your buddies doing something with/to a girl that you just automatically know is wrong, don't do that thing. Relax and enjoy the ride my friend. Remember, relationships are like trains...there will be another one along in a few minutes. BTW, chicks love a gentleman. Open a door for a lady. Don't say stupid stuff in front of her. Pull her chair out for her.When you see the opportunity, lean over and whisper in her ear that she's the best looking woman in the room. No matter how much your buds make fun of you, I guarantee you'll be doing the dirty a lot more than they will.
