Hi sorry to hear you've not had a good holiday.
I agree with don't remember. Maybe ask your son what he would like to do for your next holiday . My son and I have just had a 5 day activity holiday. Pretty intense but great fun but he enjoyed it though he's still little younger than your son.
Or Could he maybe bring a friend?I used to do that when a child.
The amends and letting resentments go also helps me . I didn't realise just how much my tension affected my son.
