I am rejecting a girl that is in a wheelchair.
Is that the reason that you are rejecting her?
No, I don't like her attitude when she asked me out.
If you think that she was rude, I can understand that you want to say no. Most people would not be attracted to someone with a bad attitude.
It's not like I won't find her attractive. It's just a no.
I can understand what you mean. It is okay to not be attracted to certain people. You can let her know the reason why you turned her down so she can start treating others better.
