As SMS says, after school and weekend courses to keep kids busy (and IMHO presumably to hope to discover a hidden talent that will make the parents rich in their old age
).
I can't really blame the parents for hoping to discover the next Tiger Woods or Vanessa Mae - I'm sure that it'd be nice (financially!) to have a child prodigy in the family but it does make these parents come across as pushy and a bit desperate.
We could never afford music, art, ballet or golf lessons when I was a child and I don't feel that I missed out.
And they're not cheap either these lessons - and they sting you with 'enrollment fees' and 'admin fees' and all that kind of hidden extra and some of them also have 12 month contracts so you're stuck with it for a year even if your kid hates it.
When children are not doing 'enrichment courses' they're often doing extra tuition in something. Parents go on about how great the school is that their kids go to and then stick them in extra tuition and I think to myself that the school can't be that fantastic if they have to take extra tuition for most of their subjects.
However, if I haven't put you off and you are ever interested in putting your children into an enrichment course - always check out the Community Centres first as they have the cheapest courses.
