Just let me be.
There is one rule that Andre always abides by, and that is- Don't stand out.
Not standing out requires not talking, so Andre is quiet. He keeps to himself and avoids contact of any sort. When he must interact, he is short and to the point. He never raises his voice against anyone, never raises a hand to anyone. He fades into the shadows like a panther in hiding. His laugh is deep and throaty and is heard once in a blue moon. Most avoid him due to his towering stance and mysterious demeanor, but he rather it be this way. If anyone chooses to attempt to befriend him, he makes it clear that he is not fond of any friend, of any sort.
If you can get past this wall of hatred he incircles himself with, you may find that he is an entirely different person. He's quirky and funny and odd, and he often chooses to lose himself in deep thoughts. He's extremely protective of those he chooses to befriend.
The reason that Andre keeps to himself is because he and his mother are constantly abused by his voilent father, and it's also the reason that he doesn't want friends; he's afraid he'd turn out like his father. His little sister, Arabell, was killed by her father, and Andre often blames himself for her death. His father has been in prison for the past three years.
