Happiness is coming home from the airport after feeling a little sad leaving the home you've grown up in and where most of your support system still is, landing 40 minutes later than scheduled and encountering an hour long immigration queue to find that your refrigerator has been stocked with ready meals and juice by your brother who has been patiently waiting in your flat to help you with your luggage, not because you're tired and ill with the flu, but simply because you're his little sister.
