Living among local people in Asia has taught us to appreciate even the smallest things. After a bit over 3 years, we already know that westerners (Europe and the USA mainly) are extremely privileged. They are surrounded by conveniences that they don't appreciate and that others can only dream about. Until quite recently, we belonged to these people.
We were there only a month so it's definitely not a complete list of weird and/or annoying things there. We'll surely come back there and update our thoughts about it. For now, though I have a full list of weird, annoying and funny things we found in Thailand in a month we spent there.
