I'm going to get one because sometimes I can't walk more than two steps without crying out in pain. I'm not excited about people judging me because I look ok. The worst part is that I have been the ignorant asshole "calling out" a placard abuser. The memory makes me cringe. Well, actually I didn't see the placard because of tinted windows and I said something because I thought it was just illegal parking, but still. :( I should have looked harder or shut up.
