Passion and Obsession

I am studying obsessive behaviours, Martin my brother will be part of my project. He is 12 years old and he is diagnose with autism since he was 4 years old. He has many habits and routines which Martin would have to do everyday. For example, he will have to use the same bowl and spoon to eat his dinner everyday, after school he will have to change his clothes then have his dinner. During bedtime he would always watch Teletubbies before he goes to sleep. I think these routines and habits are very useful for my project, because their routines are very important to them each day, and they have to do things in their own way.
