Lots of things! The time someone cried to one of my songs...that may have been the biggest. I find a lot of my students have things they want to talk about besides what we are supposed to be learning, life stuff, and I really love talking them through some of these things, much more than the class material actually.
Which song? I like getting to know my students, too, and helping them learn about life, not just English. Good job, mate.
I may post it on steemit one day, if i ever see you in discord maybe I can send it.
I'm on Discord now. I'd love to hear it.
