Quick temper, rigid must be the boss of everything, meltdown tantrums long after he should have grown out of them, easily overwhelmed, constant talking about the saaaaaaaame one subject.

Always needs to be supervised - becuase something always goes wrong and it drives him mental to the point of screaming the house down.

Welcome to the 3 ring circus.
