Never underestimate a strange boy's willingness to have sex with you, even if he doesn't seem interested in what you have to say. I'm sorry for playing that card right away, but discovering that there's a major disconnect between feelings, respect, and sex was an extremely difficult and painful lesson for me. :(
I would've loved it if someone had told me that the more confident you are, the less boys (and girls) will make fun of you (although they still will a little, that's middle school)... and the less confident you are, the more they'll make fun of you. I didn't discover that until the 10th grade and grades 7-9 really sucked.
I was a book worm in middle school. I was in National Jr Honor Society and I got straight A's. I wish someone would have told me not to listen to my mother. All throughout middle school she pressured me to dye my hair, wear make up and stop spending so much time studying.
I gave in to her pressure and started focusing more on finding my future mate. My grades went to pot in high school and I didn't graduate from college. So, I guess I wish I would have known better than to listen to a woman who never went to college and was just trying to brainwash me into giving her 12 grandchildren.
I was too surrounded by Mormons to have been able to doubt god, but that would have been a nice thing to know at 12. I could have spent all the time I spent in church, actually doing good things, instead of just learning about that Jesus dude.
Oh, I'm not talking about body building. I'm just saying to be fit enough so that the average girl will not treat you with disdain.
The woman (you would have to admit) who is into comics or D&D is a rarity. Many of us male geek types, while searching for the aforementioned rarity, would need to interact with women not of that high caliber.
Do not try too hard to fit in. Everyone feels awkward in middle school but these kids have a sixth sense when it comes to 'faking it'. If you are less than genuine they will jump on you like the pack of wild animals that they are.
