Is all of the party food appearing in abundance in the grocery stores. It's dangerous. Last night for dinner I ate mozzarella sticks and a "vegetarian selection of Indian appetizers."
People have parties and stuff in the US, but there really isn't a different and larger selection of nibbly food like this appearing around the holidays, that I recall.
Oh, and another thing. Christmas lunches with groups of friends...especially sticky toffee pud.
