I’m wearing glasses and Tonton is in the bottom row, third from the left
That reminds me of when my boss wanted me to speak with someone important at a work event. I asked which guy to approach, and he looked rather awkward and said: "the guy in the blue shirt".
I looked over and there was a group of men of whom at least four were wearing light blue shirts. One of the men was morbidly obese.
"Do you mean the fat guy?" I asked him.
He was really embarrassed but for god's sake, when you're pointing someone out, trying to hide their primary identifier just draws attention to it even more. Don't say "the woman with medium brown hair" if the woman in question has a bullring through her nose and a swastika tattoo on her forehead.
