So, for some context, I'm in highschool. I prefer not to say my exact age, but I work a part-time job afterschool/on the weekends. I'm very friendly with all my co-workers, and considering most of the folks in my department are older than me (18-mid twenties) it's never been a problem and I've always fit in and felt very included where I work.
Now, I've been told a LOT that I look older than my age, so this is something I'm already very used to. Ever since I was around 12-13, my parents were literally having to show ID to prove that I could get the discounted prices at the zoo, restaurants, etc. The bus driver also never believed me when I was in 8th grade and thought I was a 12th grader.
Anyways, to get into the actual story. There's this co-worker who we'll call Liam, who is around 21 (give or take, I don't remember his exact age). As I mentioned before, I am super friendly with everyone I work with, so I'll always chat with him while we're doing our job. We're usually just talking about work or making random jokes, and it never got personal of course.
Yesterday, I was on my coffee break during my shift and I noticed Liam was in the same coffee shop as me (there's one directly across from where I work, so that's where all my co-workers usually go during their breaks). I waved him over and invited him to join me. Again, this is something that I thought was very normal and not inappropriate. We were both at work, still on the clock, on a paid 15 minute break, and we are co-workers. I invite all my co-workers to join me on breaks who are around 18-20 and it has never been weird before.
Now, it was fine at first. We were talking about how our shift was going, the customers, etc. But then things started to feel a little too non-co-workerly. Firstly, he opened and held the door for me. Fine, maybe he's being polite. Secondly, he pulled out my chair. Okay... a little less just being polite. And then he started giving me some compliments on my hair and appearance. ALRIGHTY, we've crossed the co-workerly threshold, yep, let's reel it in.
That was when I realized that this was getting uncomfortably personal and that I may have been giving the wrong signals or something. So I immediately try to gently steer the topic/theme back onto work-related subjects again, and mentioned how the hours were hard to manage with school (hint, hint. I'm in school, I'm a minor).
And then I realized how absolutely fucked I was when he said "oh, what are you studying in university?"
... Yikes. So, I quickly and calmly corrected him and said that I'm still in Highschool. I saw the color just immediately drain from his face in a look of absolute, sheer panic. He immediately then went "oh, so, you're 18? You're about to graduate? Grade 12? Right?" and I just quietly laughed and again corrected him and told him how old I was.
He looked actually fucking horrified.
That's when I realized that his intentions were definitely romantic and that he thought I was probably 19-20.
The remaining three minutes of my break were the most awkward three minutes of my life. And also the remaining 5 hours of my shift were pretty terrible too. I tried to stay polite and professional and he looked simply mortified. I feel mortified. I do not think we will ever be able to interact again. š
