I told some of my students that I'd go to their basketball game this afternoon (they asked me to go and where they're playing is literally a 5-minute walk from where I live); I'd feel weird (and would likely be bored) if I went by myself, so I asked my boyfriend to go with me. I have no idea how to introduce him to students, though. Do I say he's my boyfriend? Do I introduce him using his first name or do I call him "Mr. Lastname?" For context, my students are middle schoolers, and it's a girl's basketball game. I've run into students while with my boyfriend a few times before, but it was only briefly, so I sort of awkwardly didn’t really address his presence at the time. As big as Chicago is, if it's happened before, I'm sure it'll happen again, and I would really like to be able to handle it better in the future (starting today!).
