My wife likes to do things for our neighbors sometimes, like making cookies or pies. But when she does it, she makes it very brief and says, "Hi! We were just thinking of you guys and thought you would like these. Enjoy!" She keeps it very brief and on point so as to not interrupt or make them feel beholding to a longer conversation. Its literally a drop and go situation. If they invite a longer conversation then she lets them run with it, otherwise she is over and back quickly. I think keeping it dialed in as a drop off and not trying to start a social visit is what keeps those situations always pleasant and enjoyable for all involved. Just my two cents.
