I suppose that's Possible. But, personally, I like getting party invitations out of the blue, from people I only dimly recall (not so unusual with a memory lie mine). It's a nice fillip, because giving an invitation is a positive act, and it implies that you must have made some kind of favourable impression them at some time.
