1. Great friends.
2. A good bowl of rice noodles in broth. (The ideal bowl is served under a tent by the side of the road, and has a good splash of vinegar, some pickled peppers (seriously), 3 or so spoonfuls of crushed peanuts, and a little bit of crushed hot red pepper)
3. My students + teaching
4. My toilet (as long as you're not food poisoned / have giardia, squatting is better)
5. Being able to walk everywhere
