This really is THE point - there is no benefit to using an ECV: You don't get to ride ANY SOONER, you don't get a better seat (most times it's in the very back), you do get on the bus first BUT YOU GET OFF LAST! You can't see anything but peoples butts, people call you names, say things about you that you wouldn't believe, and treat you like you're lazy, ugly, and a waste of oxygen, food and water. None of my illnesses are visible, but I'd gladly trade away my constant pain from osteo and rheumatoid arthritis, my exhaustion from my still working but failing kidneys, Sjogren's Syndrome, anemia, and immunodeficiency disease (CVID). But, they just see me as overweight and lazy and have no problem openly treating me that way.
What I don't understand is where civility in our society went. I don't think people always treated each other so poorly. But it has been this way for some time. I had surgery about 20 years ago and was on crutches, and you can't imagine the number of people who wouldn't open doors, or would just let them close in my face. I use a manual wheelchair here at home, and again, people will go out of their way to walk around my chair to open a door and go in, but not hold it open for me. It still floors me every time.
