It's funny, we talk about not getting more house than you need, like a guest room that only gets used a few times a year, but we never say the same thing about a dining room, which for most people I know gets used about as often, when entertaining guests, and really if the dining room wasn't there, they'd find a perfectly adequate solution (kitchen table, eat outside). That's another whole room in the house that often goes to waste that we pay for.
