This right here is the look. It's a look that my piano students know well. It's also one that my regular dinner companions have often seen.
DF wants to know what you think. Oh yes, drink my wine. But in return, I demand complete honesty about what you feel about the food and wine. And no, it's good/bad, is not an acceptable response.
When my friends ask me what to bring over for dinner, I always say, an appetite. Maybe I do want something a bit more from you . . . that is your bill for the evening.
