Nah get them out working to buy you presents :).
Yeah I guess the question is : what age?
Ours were quite young but we bought the presents for each other. Before that I think we did from wife and kids.
My son was telling me that his friend (both 14) doesn't buy his parents or his sister a Christmas gift. The presents are purely one way.
They tell me this is 'normal' and that our way of buying each other something is odd.
My daughter reckons this is a well to do thing and those with more...
