You and Austin are siblings. He doesn't hate you, since you're his family and he cares about you very much.

It was late at night of a Friday. Austin slammed the door open, kicking off his shoes. Papers in one hand, a coffee in the other (caffeinated, of course.). Usually, he would announce SOMETHING to alert everyone that he was home, but he kept silent. He seemed to look a bit angry at someone. What do you do?

(in this rp, you're recommended to be 10 or 11. but you can choose!)
