DD is also a teen, has given up Scouts that she enjoyed (time, and most of her year group left, even though she got on very well with the next year group who included her generally), swimming (she is a good swimmer, not interested in competitive or lifeguarding), soccer, gaelic, etc.
She still sails when she can (and in transition year, there are lots of short courses available, some Wednesdays, some weekends, and she has signed up for the winter racing in the harbour on Sundays, but not the training clinic on saturdays).
She is in the Lego club which is run in school but extra curricular - I think it's Tuesdays this year.
But her main interest is hockey - she trains in school (but after school hours) on Monday, Wednesday and Thursday; she has club training on Thursday nights (and could do Mondays but doesn't), school training/matches Saturday, club Ladies matches Saturday afternoon, club coaching primary school age early Sunday morning, club training/matches for her age group later Sunday morning, and then provincial training/matches on Sunday afternoons (between 2-4 times/month - hence she booked the sailing for the afternoons she has "nothing to do"!).
DH doesn't have any fixed committments (doesn't want them, and is also chief chauffeur for 15 year old with a goalie bag of gear....which fills the boot on its own, or else with all the sailing gear and equipment, which also fills the entire car...).
I have a yoga class on a thursday evening at the same time as DD's training.
And I run a Cub Scout group on Saturday mornings, which often seeps into the afternoon as the Leaders tidy up, arrange upcoming events, and keep ourselves organised - and I then do whatever shopping etc I need to do alone.
That's more than enough - I used to do the winter racing season on Sundays, but there is too much going on in our family to commit to that these days.
