Should a pool/tag be made for images that take passages directly from Wikipedia? Because I think I've seen more than just a couple of them...

When mutual humans meet for whatever purpose, discussion on the topic related to that purpose doesn't immediately start. First, their mutual forms are given confirmation, with words or gestures, or possibly both parties perform actions that let the other know that their existence is known (such as making eye contact, raising their hand, and saying "Yah").
From the Japanese Wikipedia pageon greetings.
