Don't worry! There is no need to care if people didn't want to be friends with you because of Naruto. That tells a lot about themselves and shows you how immature they are. Cartoons and animes don't know about ages. We are all children in our hearts. I know many older (muuuuch older) people who like watching cartoons. My parents are sometimes watching cartoons and anime with me! Or I find some toys and play with them! I also had a problem with watching Naruto because my friends didn't like it and were saying it's for little kids. Other things were popular (and are now, and you know what). But now I've found friends in my new class who love Naruto! And guess what we have in common: we are learning Chinese and Japanese! ^____^
I personally can't tell anything about a person who watches Naruto. If I don't like it, then I won't talk with that person about it. There are lots of other common things we can talk about! (that was an example) =D
So, there is no need to worry. You have a family who loves you and that's enough to be happy!
