If the guests want to wrest the check away from the host, because the host is also the guest of honor, then the guest who volunteers has to cover the whole thing. A guest can't volunteer -all- of the guests to pay for the host/honoree.
Carolyn HaxThere is a difference between your parents' not reporting to you everything they do and keeping secrets from you.
Carolyn HaxI actually recommend as little actual counting as possible in a life partnership. But, when there's a sense of injustice brewing between you, some counting is inevitable, and so my advice is to count using as broad a scope as possible. It's not just hours worked or chores done, either, and it's not even just about the household - it's a system of Whole Marriage Thinking. It's about hours worked, chores done, goals supported, emotional needs met, everything. What it all takes out of you, what it all gives back. It all factors in.
