I can't stand my brother with down syndrome
Why can't you stand your brother?
He made me very upset when he used my PSP and broke it.
Your brother has down syndrome. He can't help it when he does bad things. You should love him and respect him.
I have a hard time to trust him with stuff.
I understand that you have a hard time trusting him with things. But these are the things you deal with when a person has a mental illness. Maybe next time you can put things you don't want him touching out of reach of him.
