Hello.
These days I usually sit on the left side -->coming in the main entrance towards the altar → somewhere in the middle. I sit in the general area, but not a specific spot. Don’t know why I do that. At the church before, I used to always sit on the right side, sort of towards the back. At another church I’d sit in the middle of the pew in about the middle of the church. Who knows.
I know I don’t like it when people sit on either end of a very long pew, leaving a huge empty space in the middle, and people need to ask them to move.
