You are in a club with friends. Theo, who you have been catching eyes with all night, is dancing a few steps away with his back to you. The music is too loud to talk.
You would like to dance with him.
The principle
A club is not consent. Let people see you coming, give them room to turn towards you or away, and treat turning away as a no.
If this brings something up for you
