Why do people wave at planes?
Not every greeting expects an answer.
A plane crosses the sky.
Someone waves.
They know the pilots probably cannot see them.
However, the gesture still feels meaningful.
The hidden mechanism is Communication Ownership. Humans naturally transform observation into interaction. Looking becomes greeting. Distance becomes connection.
Because of this, the wave is not really for the pilots.
It is for the person waving.
The action says, "I noticed this moment, and I wanted to belong to it."
Some greetings change relationships.
Others simply remind people that even enormous things can feel strangely personal.
