I also have a madricha 2 years and a few months older than me, and she is foremost a madricha and not really a friend, and that is a different relashenship completely, and I feel like I’m 10 with her, since she is way more mature. So that can also happen, it really depends on the people involved, everyone in a whole world, it’s sorta hard to generalize what exactly the relationship will be.
But with C.I. boy, it seems (correct me if I am wrong) that most/all of his friends are that age, which, in this case, I do agree with oomis, is not very good.
Good Luck! I suggest you find some boys your age, maybe try moving schools to a more friendly and accepting crowd…everyone has their differences they could be made fun of…
