I do actually like the way they are treating her like a normal character and not being afraid to give her comedy plots. I really feel this shows blind people are the same as any one else, apart from the physical differences.
In real life people do end up in these situations and people do do these things that happens with Lizzie.
I think its very realistic and anything else would be sugar- coated and unreal, making 'Blind People' really thought of as different, and that you have to be careful how to portray them, which is not the case.
