I love when a pro wrestler gives their opponent a little rub/touch after a big move to make sure they're okay/tell the other wrestler they're okay. Especially if the move was sloppy or not executed perfectly.
It's also great when a more established wrestler wins over a young up-and-comer and gives them a tap/rub/tickle/kiss after the pin to let them know they did a good job and had a good match.
When I’m out birding and another birder gives me a tip as to seeing a cool bird. It’s always a lovely moment of connection and shared understanding, which gives me momentary hope for humanity.
I don't know anything about birding, but I love seeing Bluejays and Robins when I'm out walking, blows me away how beautiful they are.
