I remember one a few years back, shame she was collecting for a charity though! She thought it was strange me going to the library and asked what I was into, then went on about how her dad used to read her lord of the rings when she was younger, though I had never read or seen the film at the time. I was weak willed and signed up for the charity, gave quite a few donations before I cancelled it.
In 6th form a girl who had been in a car crash started talking to me when she never had before, but only for a little way before we got into school. Also some girl in my 6th form class would talk to me sometimes, the class was small so there wasnt many people to talk to, she had a boyfriend though.
I remember ringing up about something, which is a rare, I keep proffessional and think they will too but twice whilst they are waiting for something they randomly chat to me, but I think they would anyone really.
