Living in a new place in a new country can be intimidating at first. When I first arrived in my town, everything around me was new and exciting and different (and a bit overwhelming).
I found that one of the most important things I can do is to be out and about-- shopping at the market, exercising at the local recreation area, eating at food carts. This helps people get to know me, chat with me outside of the school environment, see students and parents around town, and generally allow people to see that although I am the special guest foreigner in town, I am not much different from them.
In Thailand, it seems your proximity and availability leads to invitations which lead to friendships, and a million special opportunities that most tourists would never have. Thai people are known for being incredibly friendly and generous, and reciprocating that by engaging in some simple acts of kindness like some free English lessons, entertaining the neighborhood kids, gifting some fruit, or feeding local dogs, can have a major impact.
