1. As a kid: The countdown to Christmas is a crescendo of excitement and chocolate advent calendars (but you always complained if there wasn't a chocolate for the 25th).
As an adult: The countdown to Christmas is mostly just panicking that you still haven't done your shopping but have spent all your money on Christmas parties.

As an adult: You roll in steaming at about 3am and fall asleep spooning a Big Mac.
3. As a kid: You wake up at about 5am and immediately wake up your probably-quite-hungover parents because you're off your tits on pure childish excitement.

As an adult: You drag your pounding head out of bed at 11am and are thinking more about paracetamol than presents.

5. As a kid: You've opened all your presents in six minutes flat, screamed a lot, and can't remember who anything's from.
As an adult: Opening presents feels kind of awkward, especially because there's always that one terrible gift you have to pretend to like because your aunt who thought you'd be delighted with your new shower gel is sitting there staring at you.

6. As a kid: Sprouts are the devil, here to ruin your Christmas.
