Dear LFTP: the well-to-do but cheap sister

• Should I confront my sister about her lack of reciprocal hospitality?
• What is the right way to handle the awkward check moment at a group meal?

A listener's sister and husband — well-to-do but cheap — invited themselves for three nights in the snowbird condo, requested separate checks at both dinners despite free lodging and all other meals, and never reciprocated; the wife says don't confront. The hosts advise leaving it alone: generosity shouldn't be a trade of social protocols, and you don't trade a relationship for the bill. The Secular answer is read (stay silent and roll up the welcome mat next time, or speak up — money doesn't equal class), which the hosts gently mock.
