I've found that it's actually more of a disability to be tall than short. I have no problem fitting into plane toilets etc, and the adaptations made for wheelchair users - such as the lowering of bank machines - work for me as well.
I don't think I'm really a rude person, but now I see myself on television, I think, 'Oh, God, that is a bit strong.' And I wonder if I've always been like that and I haven't been aware of it.
