Signs of being away from home for too long:

- You yelp "Where am I?" more than 5 times on the way home from the airport
- You find your bedroom taken over by a parent
- You forget central-heating does not exist in HK and didn't pack your wooly jumpers, so you end up hovering around the house wrapped in blankets OR you don't ever leave your bed
- You forget the broadband connection only functions in name, so in reality you can't get work done at home.
- The new dog mistakes you for a stranger and tries to eat you.
- The old dog mistakes you for a stranger and stares at you blankly when you call her name.
