Being close enough to touch someone does not mean you have permission to touch them.
This remains true even when the person is famous.
Do not grab the performer’s hand and refuse to let go.
Do not pull on their clothing.
Do not wrap yourself around their arm.
Do not yank them toward the crowd as though you have just won them at a carnival.
If an artist reaches toward the audience, that may be an invitation for a brief high-five, a hand touch, or a moment of connection.
It is not permission to begin a custody dispute.
The performer is working.
They are trying to sing, move, balance, remember lyrics, avoid cables, and occasionally stand near the edge of a stage without being dragged into a crowd by someone who has mistaken enthusiasm for ownership.
A person entering your reach does not become public property.
Let go.
Preferably before security becomes involved.
