I don't want to be friends with a special needs student
Oh is that so? Is there a reason you don't want to be friends with them?
She is often singing and laughing by herself and the spectacle makes me uncomfortable.
You shouldn't be discriminating against her just because she has special needs. You should be doing your best to support her as much as you can because she needs it.
She is a distraction and it stresses me out since I'm taking AP Physics.
I understand that it can be stressful at times, but people with special needs need our full support. It's really important to help them as much as we possibly can.
