I'm going to exclude my friend who has asperger's
Why would you exlude your friend?
Because he is a geek with no friends
You should not exclude your friend with disabilities just because he has asperger's. Him not having any friends would make him an even better candidate to keep as your friend. Try to get to know him a little better, and maybe youll be able to see his side of things.
So I can't exclude him from my life because he has disabilities? The least he could do is stop getting on my nerves. He doesn't do anything useful.
It can be hard to understand somebody with Asperger's but you can learn more about them if you really care about your friendship. Friendship is give and take and a disability shouldn't be a reason for not being friends.
