Am I gonna get deadnamed and misgendered at the school reunion??

So my old classmates are throwing a 10y reunion party and at first I was super excited bc I’m curious to see what kind of people everyone grew up to be. But then it dawned on me that probably over half the people don’t know I transitioned and if I introduce myself with my chosen name they are gonna be like “who??”. (We only had a class of 50 people and no one with my name or anything close to it so they couldn’t even guess tbh) The few people who follow me on instagram might know but that’s probably 1/3 of everyone and I’m not active on socials.

I guess I’m looking for advice how to navigate the situation if my name comes up. I could use my last name but even I don’t remember peoples last names so would they remember mine?? What do I do if they ask me “are you [deadname]?”

Any advice is appreciated thank u!
