I don't know why, but it happens to me a lot. One woman told me that her husband died in a mine collapse. I had never spoken to her before, we talked for 10 minutes, and the conversation started because I was working in the yard when she walked by. I never remember to ask people questions (autism), so I know it's not due to me asking them the right/wrong thing.
if you play as the dark urge character she joins your camp! she plays music for you and everything, she's such a sweet character, loved having her around =]
