Less stress and less drama

I have had to deal with my brother a couple of times this week, doing the same things I had to do last month and it wasn't too bad. I have made myself known how I expect him to be and to act and he is trying to actually do better and not be so arrogant and uncaring or inconsiderate of my feelings. Or at least he is so that he can still get what he needs form me. But I don't think that can be too much of it since what I have let him know is that he can't expect me to help him or do that much for him.
Anyway, I think maybe he is trying to be less an ass and more considerate even if it is for his own benefit. Whatever reason it is making it less stressful to deal with him.
