Son has been playing rugby for a few years now. The past couple of times they've moved up a year group they introduce more rules and he decides he hates it, it's too hard and he doesn't want to go anymore.
He had the same issue with a particular football training group he goes to. Been going for years, moved to a more advanced group, decided he never wants to go back.
As another poster suggested, we got to the bottom of it and it's the perception he has that he's not picking things up as quickly as others, or he's not as good as others that's the real issue, not that he's lazy. Maybe your daughter doesn't pick these things up straight away, sees that others are better and feels inferior or intimidated by it.
All we do is say fair enough you don't want to do it, but we've got the kit now or we're paid up until X date, so keep going until then and we'll see how you feel. So far it's only swimming he stuck with his original decision to quit.
On the subject of being lazy around the house, that's just kids isn't it? There's so much mine will do for himself, but other things he's got into a habit of asking about. Laces, top button, can you get me a drink etc. Again as other have said if you stop doing they stop asking.
