I was just thinking that we deaf ppl would be more understanding of others with some kind of disability. Since we deal with it 24/7 . Know what I mean..
But what about Deaf people who do not see deafness as a disability?
They do not want sympathy.
Also, I think you are generalizing too much here.
Saying that deaf are more sympathetic towards other people with disabilities is like assuming that because my car has a flat tire that I would be more sympathetic towards someone involved in a fender bender.
Or that because someone is a vegetarian that they would be more sympathetic towards people modifying their diet to lose weight.
Or to assume that because I am Korean that I would care more about an asian person over another ethnicity (which I don't. I don't consider myself "asian" in identity. I'm Korean and American, not "asian"). They are seemingly related but really cannot be grouped as being the same thing.
Lastly, not friends anymore due to dyslexia? Maybe there's more going on than this. Having trouble communicating accurately is one thing, but also consider that:
1. Maybe she is looking for different friends, and doesn't want this friend to feel neglected while she's spending time with new friends.
2. Maybe her friends do not like her hanging out with that friend.
3. Maybe the disconnect between her life and this friend make the relationship stressful. (long-distance! oww)
4. Maybe she has simply lost interest. It happens. You like someone, you get to know them, but then it turns out that person is not as interesting as assumed.
5. Maybe one or both of them are unable to communicate what they want effectively. I always wanted to go ride my bike and play videogames as a kid, but my friends wanted to play at home and play with dolls.
