Fortunately they are not for me.
A friend of mine is a bit ... reckless. He has a habit of skateboarding on a half-pipe sort of arrangement in the loft next to his office, and took a spill last night, spraining his ankle.
Not that he has health insurance (yes, foolish but not uncommon)
He had a pair of crutches around the office here but someone's walked off with them. (hobbled?)
Since crutches are the sort of thing that sometimes accumulate (at one point I think there were three pairs in my household, gathering dust) I wondered if someone on JC would have a spare pair that they would not mind loaning out or giving away.
