Payal's typically cannot reach most things that are above 3 feet from the ground and often get trampled on in crowded places, despite making silly noises as a warning that she's there.
Payal's also typically pop out from nowhere in surroundings with walls or obstacles over the height of 3 feet. (e.g. pop their head over cubicle walls)
Crowded elevators smell different to these people.
Bob: What do you mean when you "grow up"?
Sue: Oh yeah...looks like I'm already too big to be a Payal.
David: Hey Joan, who is that 10-year-old sitting in the cube next to you?
Ken: No, man. That's Paula, my Payal friend.
