My neighborhood or subdivision in the suburbs of Chiang Mai has a ton of houses in it. I actually find it very easy to get lost in my own neighborhood because of the fact that most of the houses look the same and all the streets kind of blend in an indistinguishable manor. There have been many occasions where I had to get google maps out in order to find my own house despite the fact that I was only a few blocks from my front door.
Anyway
I started noticing during one of my wanders that about 30% of the houses have some amount of refilled plastic water bottles arranged around their house. Since no one actually drinks the tap water here, I determined they couldn't possibly be using the sun's heat to make some sort of beverage (my mom used to make "sun tea" in my youth) and it also was not every house.
I couldn't figure out by looking around why it is that anyone would do this and I also have never encountered this during my more-than-a-decade of living in the south of Thailand.
I asked my real estate agent why people do this and even she was a little bit unsure but eventually gave me an answer.
Do you think you can guess what this practice is all about? I already know but I'm curious if you think you can guess.
