Being a middle child is fine, until your older brother leaves home and it is your turn to take care of the younger sibling. Tell them how everything will be fine, hold them when they cry, promise them school is not that bad, even if it's a lie. Talk to them about their day and teach them how to treat girls.
It's about growing up too soon and not being ready to become an adult. It's about the damn guilt you carry, because you did not spend enough time with your older brother and you didn't tell them everything. It's about not asking them the questions you had and taking those movie nights for granted.
I'm sorry I can never be as good of a big sibling to him as you were.
