In America, complaining is a normal conversational pastime.
Apparently it was my habit also.

I didn't realize this until I moved to Thailand in 2010. As I learned to speak the language I found that Thai people don't complain, do little small talk, and I kept getting puzzled looks and silence if I made "obvious" statements Americans make, like "Sure is sunny today."

This discouraged me from doing it for years, but two days ago, in a fit of frustration I complained long and bitterly to the staff in a busy clinic that had made me wait for six hours before getting seen.

I ranted that it would be so late when I left there would no longer be public transportation, no more motorbike taxis, and I'd have to walk for a kilometer along the highway in the dark to try to catch a songtheaw truck taxi at the main highway.

Furthermore, the shops where I usually buy food for dinner would be closed, etc.

The nurses nodded sympathetically, but Thai people teach their children from babyhood not to complain, so they were doubtless chalking it up to my being a foreigner.

Despite my dire predictions, the appointment ended soon enough that I was at least able to find a motorbike taxi and I asked to be taken to a Tesco-Lotus mall near my place where I was able at that late hour to get a plate of Thai food in the food court.

I guess I should have saved my breath, but it still felt good to voice some of my anxiety.
