I have Restless legs syndrome and find it very hard to sit over an hour. I sit in the back when I go and often slip out to on long sermons with many alter calls. I have explained this to the preacher and he understands. I try not to be a annoyance, but I am sure I bother a few people.
Feh. You’re an adult. You know when you have to get up. It’s a little different than with kids. Or if you made a specatacle of yourself. I guess because I was in various choirs for many years, I am used to being able to get up and move around during the service.
