I am the youngest of 4 brothers. From a very young age, we have had a great arrangement whereby we do NOT buy each other presents at Christmas or birthdays.
We also have a long standing agreement that all nephews and nieces fall off the present list at age 21 (which means most of them now).
Given that I am without a woman this year, my Christmas present shopping list amounts to about 5 people. Most of that will be smelly stuff for testosterone fueled teenagers, and/or cash.
Friday is xmas shopping day with a couple of friends. Half an hour in the hell that is Glasgows' Sauciehall Street should do it, followed by much needed stress relief in the form of an afternoon session in the Horseshoe Bar.
Mr 6's family had a similar arrangement that I was introduced to when we got together, whereby they only buy presents for the children in the family - at that time it was just the one nephew. Strangely when my children came along only his sister and eldest brother bothered to buy presents for them, and the brother stopped about 10 years ago. I don't think he understands the post office or the idea of sending a present, or even a card. We've reciprocated by not bothering to buy presents for either of his children since they came along a couple of years ago.
In my family you drop off the present list at around 18, which is a bit awkward with eldest son not getting anything now but the younger five still do.
I stopped buying a present for my nephew when he joined the army and started earning more than me!
With my own children we've started a tradition of secret santa, so between the eight of us we each buy one small present and then on xmas eve they try to guess who bought what. I cover the cost for those without income and the older ones are expected to take responsibility for their own shopping. I'm hoping it's something they'll continue as they get older rather than feel pressure to buy each of the siblings, and significant others, presents as they come along.
