Last week, Miguel (Untitled) was sick and missed class. This week, I asked him why he was absent. He, in English, said "I am no good last week" so we talked about what his illness was - got it down to stomach-ache. Told him that 'ache' means 'pain' or 'hurt'.
A few minutes later, I asked Miguel where Heiny was. He said she's not at work because she has a finger-ache. Really amazing job of making connection.
