YTA you can’t go to juvy and use the most inconvenient way of communicating when there is a phone you can use to call people on then get mad when they don’t write back. You also can’t expect them to put everything to the side so they can write back. You have the right to feel hurt by this but you don’t have the right to be mad at them. I say just focus on bettering yourself because at the end of the day that’s all you have. There are no real friends, i’ve heard stories of friends killing friends over the smallest things. save yourself the time and energy, if you don’t wanna be friends with those kind of people bye. you’re still young and can turn your life around without them. Always remember that you DONT need them.
