Reminds me of when I was getting my car's hood paint polished because there were a few scratches, we couldn't find them when I drove into the garage of the guy who was going to do the polishing because it was dark-ish, but after a while he found them and said "here" pointing to them and I said "I see" but he put his hand around my skinny arm (bicep area) and pulled me closer to him to "show it" to me, even though I already saw it because the light made it visible from my previous location adn I told him that. He didn't pull hard, kinda lightly but that gesture was showing clear dominance. His wife was close to us, looking for the scratches as well. That's why he did it, probably without realizing.
