marriages between people who started dating back in like, Jr High or early high school often end in divorce....simply because people are more foolish with relationships during their younger years

and yes, all the girls being in love with sasuke are like girls in real life who are obsessed with boy band singers

i think its kinda cool the way kishimoto messed around with the romance element between the characters in the series....with all the multiple love triangles and whatnot, and the way some people can be shallow like that is a pretty realistic characteristic too....I'm sure one of the things that will happen before this series ends is that sakura ends up realizing that there are alot of better guys out there that she should pay attention to, and maybe hook up with naruto or lee instead (prolly lee though, if naruto ends up with hinata)...then maybe ino will get sasuke and everyone's happy
