It is "What happened?".
Why would they ask this simple question?
Well, because of THIS:
It's that THING that's wrapped around my left leg in the picture above that surprises people. It's the physical appearance of my body draped over crutches that grabs people attention, and at work, it's the physical appearance of a healthy, young woman sitting in a wheelchair that startles people (hey, it's easier to move around the office with a wheelchair!).
People endlessly wonder what happened to me. Sometimes I get so sick of telling them the real story that I make up stories for my own amusement. My favorite one that I like to tell is that I tried break-dancing for the first time and now, I understand why people call it "break-dancing".
The funniest part is that sometimes, people don't even pay attention to what I say as the cause of my foot injury. They only like to sympathetically nod and do the "poor you!" face. I just let them carry on with their pity for me. That pity comes in handy sometimes!
As for the real reason of my foot injury, I won't disclose it in here...at least, not yet.
That leaves room for people to improvise and guess! Isn't that more fun?
