I'm so sick of this ridiculous high school relationship bullshit. If you don't have a girlfriend or boyfriend what's the big deal? When I was in AP Chemistry in high school my senior year, my lab partner one day admitted that she never had a boyfriend or had her first kiss and now she's off to some big college to become super successful.
I believe it has a lot to do with not having such petty distractions. I can only imagine how much better I would've done in school if I didn't spend so much time pining over lost "loves" and just would've focused on what I was actually in school for.
If you don't have one in high school, it's no big deal. The real relationships are the ones that happen in college and thereafter.
