My son had a major operation last April, he's a wheelchair user and when he can walk he uses a frame. If he ever walks again it will be a long time in the future and with aids.
He's 13 and fully aware of his condition.
So many people when we're out and about see his scars, and the first thing when they see him ask when is he going to walk again. They know nothing about his situation and his wheelchair gives him freedom and independence. What if he never walks again, that's no biggie to us so why do people assume that's the most important thing?
So if you must comment on a person in a wheelchair please don't say 'bless' or treat him like anything other than a 13 year old boy and don't ask about his journey, you never know what the person is aiming for.
