People disappear so quickly here. Most of the people I've met are on short 3 year contracts, which means just as you start to get to know them they're on their way out.
Goodbyes are turning out to be pretty low key as a result. No gifts, because their shipment already left. It's very strange, but apparently it's the way it is around here. One long term resident told me soon after I arrived that she wasn't in the habit of friending expats because their contracts were so short that it was like having pets - they passed on so quickly that it was too painful to have them in your life.
I haven't yet wrapped my head around this yet.
