Someone at home tilts their head. You think it means yes. Another person thinks it means they are listening. Before deciding, ask what the person intended. The movement you saw and the meaning you guessed are different things.

A gesture is a movement used to communicate. A convention is an agreed or learned way of doing something. Research finds that the link between a gesture’s shape and meaning can vary across cultures. A signal that feels obvious to you may not be obvious to a visitor.

That does not give us a dictionary for every person in any country. Keep your family observation specific. Write, "My partner said this meant..." rather than, "Everyone there means..." The puzzle invites you to check a message. It does not ask you to copy unfamiliar signs or guess someone’s personality from the way they move.

Imagine agreeing that a raised open palm means pause in your game. After agreeing, both players can use it. Someone joining later may need the rule explained. The movement has not changed, but the shared knowledge has.

Now imagine a different situation. The same hand could be part of a wave or a request to take a turn. The surrounding action is a clue. Research on conversation also finds differences in how gestures, including nods, are used politely.

Your invented code is not a custom or greeting from any particular community. It is a small model of how a shared meaning can help. When a guess fails, ask a question, show what you meant or use words if you can. A mismatch is a reason to clarify, not a reason to decide that someone communicates badly.
