For years, I pulled one of the worst moves a dinner party host can make. And no, I don't mean I apologized to guests for the state of my house even after I spent all day dusting and decluttering (though I definitely did and still do that). I mean I would text someone who was already en route and ask them to pick up a bag of ice. I realize nobody wants to get that text, and I swear my requests were never premeditated.
