Whatever floats yer boat I say!
No kids here, so I suppose I have mine all wrapped up too, because there are none! Just cash to the under 18s niece and nephew, just two of them left under 18 now.
Siblings do not buy for each other, and friends have agreed the same. DH and I do not buy for each other either, but we go away for a week post Christmas instead.
It is an individual thing, but it suits all of us. Haven't heard any complaints apart from sighs of relief all round! And we are saving the planet from tat, plastic, wrapping and landfill. So may I be smug too, lol...
Enjoy your Christmas YOUR WAY x
