The Church of Susan's Experiment is interactive which is something Susan is not comfortable with.
In that other church, one could slip in unnoticed, sit in the back & scoot out early.
The building is small and a family of four arriving late will have all available eyes upon them as they take their seats.
Up front, because the back rows fill first.
In addition, someone will come over to let them know that bored youth might prefer to go downstairs to Sunday school. Susan's bored youth want no part of this.
Early in the service the congregation turns to greet one another, they do this with a handshake, a nod or by walking over from the other side of the room to say hello. After service the pastor hotfoots it outside to chat as everyone exits just like Susan has seen done in the movies. Anyway, her point is that she's not getting out of there before having to speak with a person or two every week.
On the plus side, the Church of Susan's Experiment is adorable. A real charming white clapboard country church set on a winding road with a cemetery. The lady pastor is interesting to listen to and Susan likes the church's inclusiveness and charitable projects but she's a long way off from joining anything.
