He don’t like the colours brown and yellow and he hate being touched. If someone touch him the person might be beaten. Christopher also like dogs a lot because they don’t have such difficult way to act like humans. And dogs can’t speak so they can’t tell lies and that’s pretty awesome he thinks.

When Christopher get’s nervous he hold on his ears so he could shut the world outside, out.
