Brittle seems reasonably applicable. With Jon Cox's OP in mind, in my teens it was a learning curve to realise that just because people grow older/bigger, they don't always behave like adults 'ought to', they carry on being unreasonable, or childish, or what have you.
A brother neatly put it as 'Just because people grow older, it doesn't mean they stop being bullies like they were at school'.
