Age difference
When I was a freshman in high school, I liked freshmen.
When I was a sophomore in high school, I liked freshmen.
When I was a junior in high school, I dated a freshman.
Now I'm a senior in high school with crushes on multiple freshmen.
I think it could have something to do with my lack of maturity.
Maybe it's something to do with the fact that when I was in ninth grade I had a tragic even I never really dealt with fully and coming back into society was like landing on the moon.
I know a guy who dated an 8th grader while he was a junior, so I try and take solace in the fact that I'm not alone and that twenty years from now the age difference would mean nothing
