I try do do most of what you suggest. As for sarcasm I try not to use it where learning is involved. However, when it involves silly questions intended to distract me or disrupt the lesson I can't help it.

"Is that a picture of your wife?"
"No, I just put up random pictures of Asian women."

"You're wearing shorts today."
"Oh my God, I've lost half my pants!"

"The music from the other classroom is bothering me."
"The wall doesn't have a volume control."
(They say this without any consideration of the noise we make in our room; which is sometimes considerable.)

Today we had some friends over for dinner. Wakana had assigned her students to call her to invite her to join them somewhere (their choice) using only Japanese. We all planned to answer the phone in Japanese so they would have to ask for "Burnham-sensai" which only increased their nervousness. One problem they had was that three of us were sensais and two were fluent Japanese speakers. The possibility for confusion was enormous.

None of her thirteen students did call and we took turns answering the phone. I had an image of teenage boys all over the island making the call with shaking hands and breathing a big sigh of relief when it was over.

In preparation for the gathering I took a 2 quart plastic pitcher and a pair of kitchen shears out to the calamansi tree and filled the picture with little orange citrus fruit. As I worked I reflected on the November temperatures back home. I was happy to be where I was. I often think on Gordon Bok's comment in one of his music books about the hills in November offering as much comfort as a cold iron crowbar.

My mother managed to get together a bunch of books from the Carey Library in Houlton, Maine, which she sent to me. I had the best artist in class create a thank you card (butcher paper about 30" to a side) and the students signed it on Friday. I'll mail it out on Tuesday. It looks pretty nice. Need to take a picture.
