I can tell by your accent.

We've been talking for a few minutes by now. "Are you from Germany?" "No, Ukraine". The guy smiled and added with what seemed like a little bit of pride, "I've noticed by your accent". I didn't know what to say next, so I tried remaining neutral and proceeded with a brief "Okay".

This wasn't anything new. I've had exchanges just like that many, many times
before. "Sorry" - to my great surprise he appologized. I wasn't sure if he figured out that his pointing out about my accent reminded me once again of my "foreignness" and made me a bit insecure. Perhaps, he sensed some sort of slight awkwardness and dropped his "sorry" just in case, but we both kept quiet for a bit before I shrugged, "That's okay".

I sense that there is something wrong with me thinking this way, but the talk I described above reminds me of a situation when a person asks someone else "Hey, do you have Tourette's?" And after they respond positively that person would gladly add,
"I can tell by your tics".
