When someone takes the last roast potato.
After you’ve opened all your Christmas cards from distant relatives.
When someone suggests going for a walk after Christmas dinner.
When you have to turn the TV off because the adults want to talk to each other.
When your sister gets everyone perfect presents, AGAIN.
When you’re about to build a hotel on Mayfair in Monopoly.
When you eventually lose Monopoly anyway.
When you’re enjoying a Boxing Day snooze.
