I was helping a student last night. I returned home at 1:30 PM.
Three students are going with me to Las Vegas. I am daily instructing two of them.
Japanese do not speak English. Logically, neither do my students. They are good researchers, by the way.
Correcting manuscript is my work. Katya helps them learn to speak English once a week.
In spite of our efforts, presentation in English might be a bit beyond their present ability. So I write their speech notes, and help making their PowerPoint files. I hope they will make good talks in Las Vegas.
