I often talk about the “Grandma rule” for travelers. You may not like Grandma’s Thanksgiving turkey. It may be overcooked and dry—and her stuffing salty and studded with rubbery pellets of giblet you find unpalatable in the extreme. You may not even like turkey at all. But it’s Grandma’s turkey. And you are in Grandma’s house. So shut the fuck up and eat it. And afterward, say, “Thank you, Grandma, why, yes, yes of course I’d love seconds.”
