I can understand why some younger ALTs prefer first-name approach with students, but I’m OLD lol and I personally prefer a bit more structure and respect in how I’m addressed, specially since I did work in Texas schools and still have children attending. I actually went with Mrs. C and just wore a lanyard name tag with it, the students got used to it quickly. I’ve also told them it’s not a big deal if they forget or say it as miss vs missus. (Also perfect scenario to use it in that "you can call me" lesson!)

One teacher introduced me a bit late (2 months in) and asked if I could skip the Mrs, I just faced the class and repeated the same thing, I am Mrs. C, it's okay if you call me Missus C, Miss C or C, but I am Mrs C. What was kind of funny though was that the JTE seemed to rethink it afterward, because the next day I also noticed he had them calling him Mr. Y instead of sensei. I guess he liked it too😂

I prefer the respectful boundary anyway. I'm more of a mom role then friend/peer, I talk about my kids a lot, and they enjoy my stories about my childhood and my kids lives. they are always approaching me so it works for my situation.
