If I have the option to sit down, I can endure quite a lot. But if I'm walking around, not so much. I once got a pair of new boots, and took them out shopping. They hurt so much I litereally couldn't walk another step, and ended up having to sit down next to a fountain in the city. Then some annoying guy sits down next to me and tries to start a conversation. He was pretty creepy, really, so I told him I had to go meet somone and walked away, nearly in tears because of the pain in my feet. haha.
