Does anyone know if one is expected to buy something at those home-hosted parties? I just moved into a neighborhood, and the woman across the street gave me an invitation to a "jewelry party." It's really not up my alley, and I don't want to spend money. On the other hand, I would like to meet a few neighbors and I don't want to seem unsociable. Is it better to not go if I don't want to buy? I'm not sure what the protocol is at these types of parties, since I've never been to one. Any ideas?
