"I brought you a present."
Dad proffers a pizza cutter. It has come free with wine. We already own three.
"No, thank you."
"Also there are some of these." Two wine coolers. Also free with alcohol.
"Er. You can buy those at home."
Later; I'm packing. He brings in eight steak knives. I put them in my bag, resigned.
(They did not come free with the wine).
