The seat you leave open

At a class or lunch, a newcomer stands holding a cup. You remember a similar moment, but are unsure whether approaching would feel intrusive.

“There is a seat here if you would like it” gives them an opening. They can accept, decline, or keep looking for someone. You do not need to decide what they must be feeling.

Introduce yourself and explain the thing everyone else seems to know: where the materials are, how the session starts, or who to ask about joining. Practical information can make an unfamiliar place easier to navigate.

If they sit down, ask an easy question about the shared activity. Avoid turning their arrival into a public introduction unless that is how the group normally works and they are comfortable with it.

A greeting on the next visit can continue the opening. You are not responsible for creating instant belonging. You can help make one familiar face available.
