Double standards.

My dad can be so cool but then he can also he the most nastiest person ever. Anyway my brother (20) he always play fights with us and when he does will my littler brother (12) it's okay but when I do it i get growled or whatever like he always fucking makes me do everything around the house and as soon as I don't he goes on about how I don't do anything and here my brother is doing NOTHING, yeah he works and I don't but still? It fucks me off. I just need to rant.
