Why is my friend acting like this? Male 14?

Hmmm, he is 14 and prob very immature... But, are you a better skater do y'all compete... Cause if you hadn't done something he's thinking about something. But put yourself in his shoes... Maybe the people he was with don't like you or maybe not... But If you were him, and you blew someone off and then seen the person you ditched and being young you'd run too right?
