Summer Dilemma

Hey All. I got this problem. I wanted my friend to visit it me. My friend from Alabama(Nic, of course). Well since we are both aspies we both have different social issues. These issues clash. She doesn't want to come visit me with out anyone coming along. Her mom won't come along nor will her step sister. So, she wants to bring a friend. This one person in particular named Amanda. Amanda might be autistic but the thing is the stuff she does makes her seem normal and cool. I'm not and I'm very different. I don't want her friend thinking I'm weird and retarded. We are both into different stuff. Also I may seem sheltered to her, a loser, and a geek. My friend refuses to go by herself and Amanda is her only choice now. So yea i guess she wont come and im sad because of that. I soooo wanted her to visit but since our issues clash it wont work. She doesn't like going by herself and i don't like being around autistic people who can be normal and cool and make me look retarded. So yea I'm sad. Is there a way i can have my friend come and NOT bring her or should i just say forget it? What would you all do? I know i REFUSE and i mean purely REFUSE to meet Amanda. I don't want to stress my self so much i have a nervous brake down. Believe me it wouldn't be pretty. So yea i guess she can't come :( I need to convince her to come with out her. Any ideas? Please help! Leave a comment to what i should do all please.
