My oldest two are 8,9. Karate is twice a week, Tuesday and Thursday. It's quite late and bedtime is no sooner than 8.30 on these days.
I do nothing, I don't work and have few acitivites, none, outside the home. I used to sing in my youth, I love it, and have an opportunity to sing in Rock Choir on a Thursday. It would mean boys cutting Thursday night Karate, no other option on lift share or babysitting.
I really want to do it but feel guilty about cutting their class.
DS1 also does drama at the weekend and they both do tennis on a Saturday afternoon, French club in the week after school and DS1 does football.
