Please Leave by 9 Grumpy Cat Greeting Card

The perfect birthday card for anyone who still enjoys a party, provided it ends at a reasonable hour.

Come over! Have a drink! Eat some cake! Absolutely stay for a bit. But at approximately 8.45pm we're going to start collecting glasses with increasing determination and saying things like, “God, is that the time?”

“Please leave by 9” is for the stage of life where you genuinely want to see your friends, you just also want them to go home.

The exhausted-looking birthday cat understands. He's put the hat on. He's lit the candles. He's fulfilled his social obligations. And now he'd quite like to wash his face, put the dishwasher on and be in bed before ten.

A birthday card for introverts, tired people and anyone who has finally realised that the best parties have a clearly defined end time.

You can come. Just don't settle in.
