You can tell if they keep on doing these hand shakes and every time they see each other they kind of a hug a little bit.But if they don't know each other or don't know each other much,they maybe might look into each others eyes and just gaze for a while.Then when they hear their name or hear something that's loud they just get out of the gazing point then just get back to themselfs(normal).
