Q: You ask your in-laws over for Thanksgiving and they accept–but then ask if their extended family (about eight others) can come too. Do you have to say yes?
A: You’re not required to welcome the crowd (guests don’t normally invite others), so a friendly “I’m so sorry, but we’re not set up for that many people” is fine. But it’s Thanksgiving, so why not make room? Just ask for help up front: “Could your sister bring a pie–and I’d love it if you made your amazing sweet potatoes and an appetizer.”
