I may be strange to some people but I feel really uncomfortable when people ask questions about my personal life. It's fine to ask about my job, if I have siblings, where I live etc but there are some questions I find difficult.
For example when people at work ask me who I live with, how I met my partner, and then questions about said partner. I don't like being asked questions about my dating life. Is that odd? I know some people tell everyone their life story but I would rather not!
