Thank you!

I think this could well have been a great deal of Sirius' personality too.

I agree--it's a tendency I see all the time in spoiled kids. I mean, to be honest nearly all children will instinctively try to bargain and compromise, because in a parent & child or teacher & student interaction, the child doesn't have any power and they will do whatever they can to change that. I don't know if Sirius ever grew out of this behaviour.

mmmmm power dynamics.
