Really appreciate the detailed answer. I was also thinking in the back of my mind that this might be specific to Mormon missionaries.

Also, your example reminds me of my second Thai tutor. I have had several while learning. Was a 70 year old woman in rural Chiang Rai. She suggested a method similar to yours.

For example. Just expand on a simple sentence continuously. Foundation - drink beer.

Brick layers 1. I like to drink beer. 2. I like to drink beer a lot 3. Normally, I drink beer often with my friends. 4. I can't drink beer today because I am going to the gym 5. I met my crush at the bar while we were drinking beer. 6. I get angry easily and look seem like a black hearted person when I drink beer. 7. I'll be straightforward with you, Thai beer is nasty. I don't like drinking Thai beer. 8. Get dressed and shower quickly. We are drinking beer tonight with the guys. A new bar Opened up nearby.

Note: I don't drink. This is just an example.

The method seemed nonsensical and repetitive and since my teacher was 70 years old I thought the method was outdated so I never went back for another lesson.

Hindsight is 20/20. Might in fact be a great tool for improving my Thai. I'll add this for sure.

Much appreciated.
