I used to work in a chemist's shop that sold toiletries, and you wouldn't believe the number of men who rushed in on Christmas Eve, looked round wildly, and said "I'll take that'. No thought at all.
That is bad and must lead to a lot of very disappointed wives, who have put so much thought and effort into everybody else's gifts.
I suppose it's a measure of how much interest things hold for individual people and whether they see it as a huge joy to be meticulously planned and executed so as to bring huge pleasure or just fulfilling a basic function.
I daresay that, for some men, actually remembering, taking the time and making the effort to go to the late-night chemist or the 24-hour petrol station to buy any old present is them genuinely showing how thoughtful and caring they are, as they otherwise wouldn't bother at all, but they know 'it's important to the wife'.
For want of a crass description, I suppose you could see it as a 'hobby' that either thrills or bores somebody. Look at the hours of research some people (mainly men) will put in to deciding exactly which car they want to buy, all the minutiae and tiniest little details comparing the relative specifications and trivial options, whereas others (mainly women) will turn up at a big car yard and say "I need a decent-sized family hatchback" and take whatever the salesman suggests after a cursory look and a quick test drive. Neither way is right or wrong - it's just where your priorities lie.
Hair is probably the starkest indicator of this. Of course, there are men who are greatly into the intricacies of different styles and there are women who couldn't care less, but 95% of women see their hair as something to be looked after, thought about, carefully styled and worth spending a lot of time, money and effort on. 95% of men will ask the barber for a short back and sides, pay and walk out thinking 'job done for a few months' - or even just get the razor out at home and give themselves a 5-minute buzz cut.
If we're honest, for many things, there's a very broad spectrum of ways to do them and, to an extent, you can put in as much or as little effort as you like and not necessarily end up with a hugely different result. Not to say that you do the bare minimum, but you also don't have to feel bound to perform 'the work of a moment' like the crazy shop assistant in Love Actually.
Unfortunately, though, the difference is that many hobbies are 'selfish' things - not in a bad way, but designed for the individual to enjoy and take pleasure from.
Christmas is usually a family event and it isn't just about what suits you best. If you have children, it's an intense snapshot of daily family life. Just because you as an adult couldn't care less about Paw Patrol or potato printing art, it doesn't mean that these things are never enjoyed in your home, where there also live people who do love them and to whom they mean an immense amount.
That said, if children aren't involved, I don't see why one member of a couple automatically gets to say how it 'should' be done and criticise the other for seeing things differently.
