Like most of the questions in this thread, it's not really about the answer - it's about uncovering potential lines of discussion.The uber banal 'so up to much this weekend?' from work mates shits me to tears. Really, what are you supposed to say in response, and why are they going to care?
Banal open-ended questions are necessary when you don't know a person that well, or haven't seen them in a long time. It helps you identify what is of interest or relevant to the person's life, and then hopefully through that you get onto a line of discussion that is actually interesting to both parties.
It's mostly weird to me how many of the questions in this thread centre around people's dislike for talking about themselves. If you're going to interact socially with other people you kind of have to do that.
