Rule #1 for a Teacher: Always ask your student what they think, because it usually makes everybody happy, starting with you.
An example? I asked some students what was their favourite word in English, and Guru Charanjeet Singh from Brazil wrote:
“My favourite English word is “butterfly” because it makes no sense. Butter = thing that you put on the bread. Fly = annoying bug. It makes no sense.”
Well, it made me smile for hours.
