The realisation creeps in Large On Black
A friend of mine was in a wheelchair for a short time [following an operation] and I recall them describing themselves as an apparent inconvenience to the majority of the rest of society; for every kind hearted person there were legion more to replace the sentiment, who would roll their eyes if you got in their way. And she became invisible when I pushed her... virtually everyone would address any questions toward me first. And, if I played along, they would often ignore her completely. I guess, as with anything, you get used to it, develop a thicker skin, but I know she couldn't wait to get her metaphorical legs back and be treated like a 'normal' human being again - so much so, the actual recovery process became secondary.
