DS' last sports day at junior school in 2019. It was awful.
He hated it, the head teacher was especially bullying & spiteful, and my 10yo ds quietly said to me on the way home that if he ever had to do that again he would kill himself. Not a good day.
Things are much better now. Decent school with sports teachers who actually know what they are doing, ds now happily taking part in assorted sports.
But by tacit agreement I don't go to sports day, and ds knows if he wants to miss it, I will pull him out for the day.
If you mean professional sport, Reading FC's first game in the premiership 2006 I think. I took some customers to watch it.
Or volunteering for the local park run. I don't like spectator sports much. They always seem such a waste of time.
