Is it normal for a teen to like to watch cartoons?
Introduction: I'm a 17-years-old teen that tends to give a shit about what others think of me. Sometimes I wonder if I'm a normal guy (or not).
A few month ago (July 2018): I and my cousin were deciding what to do, he suggested we could watch some TV, I didn't have better ideas so I accepted his suggestion, I used to choose the channel we would watch, but that day was my cousin's birthday so I let him to choose the channel, so he chose Cartoon Network. I was never interested in CN, I barely watched that channel. My cousin is actually 18 and it seems he still watches cartoons, he likes Steven Universe, Adventure Time, Regular Show, Gumball, etc.
When he turned the TV on and switched to CN, Regular Show was about to start, we were watching some episodes, the plot was interesting, the show was entertaining. It was the first time I've watched a CN show, after watching some TV with him, the first thing I thought was 'meh', I wasn't interested enough.
When I went back to home, I did something very unusual, instead of using my PC, I turned on my Smart TV and switched the channel to CN only to watch more Regular Show.
It seems I was gaining more interest about CN shows, but I haven't noticed that yet.
This was unexpected:
A week later, I've become a big fan of Regular Show, I've bought some RS-themed T-shirts, I've changed my PC and phone default wallpapers, and I've even made some fan-art. This does not end here: I've downloaded some episodes to watch RS on the go and I've even downloaded some mobile games both free and paid. In a nutshell: Regular Show became my #1 favorite show.
I also watched other CN shows, but I preferred Regular Show over the rest of the CN shows.
When I realized I wasn't the same, I thought "What's happening to me? Is there something wrong with me? Am I weird? Am I childish? Have I become like my cousin?".
Instead of telling about my situation to my parents, I was looking for answers online, I've asked on Quora, but nobody gave a shit, I hope you guys give some useful answers.
Since then I was wondering: Am I childish? Is this normal?
