There's a guy I see every so often going to/from work he does shifts, so it varies. But we only see each other for a few minutes at a time and familiarised ourselves to be cordial and say hello/how are you.
At my work over Christmas, we had various other offices visiting so we were all given name tags with our name and role. Due to never wearing them, I'd forget to take mine at the end of the day. Fast forward a few months later in March, and I saw this guy often within those months, one day he said "You alright, /name/" and it threw me, I looked at him for a long second wondering if I had forgotten a whole conversation where we exchanged names, I said "pardon?" and he laughed, he said "your name tag, it's a good thing I don't wear them", the next time I saw him after that he said my name again, and gave me his name.
We still see each other, and he always says my name. I feel it's often unnatural "Good morning, name", "hello, name", "good afternoon, name" and when I respond it feels unnatural to me to use his name but I do so as a form of acknowledgement.
What impression do you get/what does it mean to you if a guy says your name often?
