I was into cringyyyyy stuff… like cheesy boybands such as One Direction, Lawson and Union J.
And I was also very into chocolate… I would buy two 100 gram bars every day and eat one whilst at school and put the other one on top of the radiator when I got home so I could eat the chocolate melted… I was gross 
(but creative)
Playing touch footballl in the streets. Or sitting in my friends room reading comic books. Watching my friends getting all the girls while the girls ignored me. Poor me. Riding bikes of course.
Oh yeah, how could I forget, I was really into baseball cards, and sometimes playing baseball with my friends. It’s a shame I never played little league.
I had a miserable time when I was 13. I don’t recall liking anything at this time. I remember a girl I kind of dated in that I asked her out, she never said yes, but she cried when her friends asked if we were going out and I said no. I remember saying I wanted to be a basketball player but I hadn’t played basketball in a few years and there was nowhere/no one to play because I played street ball. But I was still the best when we played in gym class. All this was overshadowed by the bullying my step-mother gave me constantly every day.
I also had a bad time at 13. It was just after my first major depression episode and I still had a lot of problems with depression. I was also bullied a lot at school and never fit in. The teachers and students hated me and I never had any friends.
I was interested in skateboarding and ESP. I read lot of science fiction/fantasy books involving ESP. I hated all music, but loved to draw and build things. I used to build these long marble runs out of tinkertoys, legos and capcella.
i liked playing football with my friends. Its also when i got into running. And I played a decent amount of video games. At 14 is when i had more fun sneaking out whenever i wanted
The library.
At 13 I knew everything. Senility set in sometime after that.
I was into WWE wrestling, but not anymore. lol
Pretty years i was in
Thanks god i lived a good year!
Dungeons and Dragons and starting to find music like Pink Floyd. The “Wall” fascinated me at that age!
I just wandered like a thug wearing a cap and listening to rap.
One day me and my two friends would be playing hide & seek with the cute neighbor girls Then on the weekends we’re drinking beer and making fools of ourselves. Weird times.
13 was actually a bad year for me overall. I did a lot of fun kid things but it’s also when my only two friends turned on me and started verbally tearing me apart. It was pretty bad. Sometimes I think that the harassment I faced as a teenager was worse than schizophrenia symptoms. It’s hard to say. It really got to me.
I was into browsing chat rooms with our awesome shitty) dial up and getting hit on by pedophiles.
Oh,
Forgot to mention that!
diablo 2 & disturbed
13 was when i discovered p0rn
Between the ages of 8 and 14 were my happiest years, I was truly happy back then. When I was 13 I have a lot of memories associated with Maroon 5 and Coldplay. Their Songs About Jane and X&Y albums were excellent. I also enjoyed Black Eyed Peas. I used to crash out in the garage with my mates and put black eyed peas on and just chill and have a good time, all gone now, the mates, the happiness. I also enjoyed simulation games, I’d play sim city and sims 2 for so long.
When I was 13, I was into boys, Avon perfume and makeup, dolls, (still), my cat: “Orphan Annie”, my friends, pop music, television comedies and dramas of the 1970’s, movie’s of the 1970’s, my siblings, my grandparents, and sunbathing.
At 13 I was into adventure books (by Sir Walter Scott, Karl May, Jules Verne, Alexandre Dumas, etc.).
It was around that time that we first got cable TV (before we would use an antenna and only catch the national tv channels). And I discovered Sailor Moon, a seminal shoujo anime. I was hooked!
I hadn’t yet drank my first beer, nor smoked my first cigarette. That didn’t happen until 2 years later.
And as shocking as that may sound, I was still a virgin 
Online gaming.
