Yesterday Takai Sensei asked me how to use an insulated tumbler. You know, those insulated coffee containers with the sippy hole... At the end of the year Japanese stores fill with huge "grab bags" of mystery products for a set price low. These can be anywhere from 10$ to 300$ bags, depending on the store. Takai sensei bought a Starbucks mystery bag and got a mug, an insulated tumbler, a small lap blanket and some other stuff. He knows that I have a similar tumbler because it comes to school with me every morning.
He pointed at it and asked me what I kept in it...if the coffee came from home or from Tullys...was it hot or cold....We honestly had a discussion about it keeping hot hot, cool cool, and protecting your hands from the liquid inside. I discussed drinking coffee while walking, or the fact he could fill it with what he liked, coffee or diet soda, and drink and drive his way to school. Then he explained why he was askign all these questions. He is now convinced that he got a very good mystery bag.
I didn't talk to him about priming the tumbler on cold mornings with some boiling water, he's not ready for that yet. Baby steps.
