My girlfriend broke up with me coz I stole her wheelchair But I knew she'd come crawling back to me.
I really find your joke about handicapped people to be distasteful.
I think she was relying too much on me and I needed her to be more independent and maybe then she won't rely on me for everything. Disabled people should live in their own houses and do things nicely by themselves.
Jokes are fun, but the punchline of your offensive statement attacks a group with less power within society. Hiding a hateful comment behind a joke only serves to cover up the underlying anger and motivating feelings are still there.
