Just a comment-- we all have no way of knowing what Grandma Arias' health issues may be. She is clearly elderly. She may be a "cardiac cripple" or have respiratory disease that prevents her from exerting herself over long walks. She may have joint issues, or other balance, coordination, or stamina issues. There is simply no way to know just by looking at her and making a value judgement. I hear people all the time making judgements about whether or not they think a customer "needs" the handicap sticker, when they have no obvious orthopedic impairment, and it is upsetting. Many people have debilitating illnesses that limit their ability to get around. My mother suffers from multiple sclerosis, and for years, was subjected to thoughtless comments and snickers from some bystanders thinking she was drunk because she could not walk without staggering. Now she uses a wheelchair and a walker, and is perceived as elderly and ill, not publicly drunk. (Bystanders are much kinder to her now.)
I have no problem at all with Grandma Arias using a wc full time, or part time, as she needs it. We have to remember how incredibly stressful this whole situation is for an elderly person, whose husband is so ill he could not make the trip. Just look at it this way-- the wc preserved her strength and safety from falling enough that she could be there at the trial to support her daughters and granddaughter. I am totally okay with that. I hope no one implies anything beyond the fact that clearly Grandma Arias felt she needed the wc, and not that she had some hidden sympathy agenda.
