Value Village

I was at Value Village with Sean and an old man was trying on shoes and asked Sean to help him get a boot off.  Sean immediately asked, "Are you bleeding?", which I thought was odd.  Then, when he pulled off the boot, I could see his legs, which were swollen and hard.  There was a ulcerous wound on his shin, and he was not wearing any socks.  I'll never try shoes on there again.
