I did, in fact, experience a smile.
We also learned an awesome new phrase at Japanese class: 一夜漬け, "ichiyazuke" = "one-night pickles." Pickles have to be made long in advance, so they can marinate effectively in the vinegar. But if you get lazy and forget about your vegetables, throwing them into a jar to pickle at the last minute, then they turn out really, really bad. It is quite similar, in fact, to what happens when you don't study for an exam until the night before. So "one-night pickles" is Japanese slang for "last-minute cramming." Awesome!
