I know the feeling... sucks, but I'm being homeschooled. My oldest bro has been going out a lot lately and I've been stuck pulling his weight for the last month. My only real freetime to draw now is late at night.
I normally would divide that time to playing KH2FM, Dissidia, and drawing. but he recently killed my PS2, so KH2FM isn't in the list, and he put the Ouya, where I play Dissidia, in his room, which is also mine. I spent nights in the living room. Cuz I'm always up late, babysitting anyway. Autistic sis.
