I'm sorry snow dragon, but I'm really having a hard time understanding this. You were able to wait 30 minutes, but you never sought out an alternative bathroom? I understand having a full cast is hard (and I'm impressed that your doctor is allowing you to swim in a competitive lap lane!) but this seems just a bit outlandish. I've met some evil people who likely would do that, but I'm not sure why you didn't take your crutch or anything else and start wailing on the door after her snide comment. Or for that matter, head to a different building or floor on campus. Or call campus security. If this truly happened the way you say, you and your friend should be heading to students with disabilities and lodging a complaint about the insensitivity of your fellow classmates. Twice in a short amount of time is just ludicrous.
