Walking into a room where you know nobody is a skill. It gets easier every time you do it.

Treating this as a personality test makes it permanent; treating it as a skill makes it trainable. The moves are learnable: who to stand near, what to say first, how long to stay before leaving is fine. None of them come naturally the first time and all of them get easier with repetition. The discomfort fades because the room stops being unfamiliar as a category, not because you became somebody else.

Go to one thing this month where you know nobody. Arrive early, before groups have set, and give yourself permission to leave after half an hour.
