Having a Laugh and Joke
Some people think that it's wrong to take the mick out of a person's disability, but when you are just messing around and the other person is joking with you, personally, I don't see the issue with it.
You have got to have a laugh sometimes. Me being me, I take the mick out of my own disability, for example; I have poor balance, and when I over balance, I fall over most of the time and I usually laugh it off. My mum and I laugh when I start to over balance - it is quite amusing because I sometimes end up slowly falling to the floor and I look like the Leaning Tower of Pisa!
