I have a disabled cousin, who has a shocking quality of life (from an outside POV), she's 22 and has the body of a 12 year old (i.e. not grown), has never walked, spoken, can't feed herself, and basically has no awareness of what's around her (from what I can tell), she hasn't done anything but been a living body. It was a complication or a mistake by the doctors at birth, can't remember. However I get very sad when I see her as I think "what a waste/shame". However, things like Timmeh - is funny, I don't know why, it's probably the shock factor, and I find it amusing if it's done for a laugh and not in a vitriolic way. Most people are intelligent enough to know that most people are generally sensitive to other people's feelings and that in spite of rather public vocal mickey taking mostly it's done with no malice.
