In my personal opinion, I think Valentine's Day is sorta unnecessary. It's a day where you're peer pressured by corporations and the people around you to buy **** for your S/O. If you want to give your S/O a gift or take them out on a date or whatever it may be, you can do that literally any other day of the year. Like sure, it doesn't hurt to celebrate Valentine's Day with your S/O, of course, but like Sheila (and maybe others idk) have said, I'm annoyed by holidays in general that are just basically excuses to fill the wallets of corporations.
[note: not necessarily aimed at you, just the context of that idea on Valentines day]
To an extent, I agree that you should be showing your s/o that you love them every day rather than just one day...But I think we all know this and most people already do that. Practically every holiday these days exists to make corporations money more than anything else, but I don't tend to see many arguments with that context against Halloween or Thanksgiving, two other holidays that line pockets more than anything else.
Not every couple does something significant every day of the year. It's not reasonable to expect that with the time and/or financial hurdles the vast majority of people have to various extents. After possibly working full time jobs
(maybe with different shift times, maybe multiple jobs), caring for children, taking care of the household and various other commitments people have, there's couples who just won't have the energy or motivation to do things like that as regularly as they might want to and it probably is disheartening for many of them. "You should be showing them you love them every day of the year" may as well be the fairy tale ending of a classic Disney movie for how much the "hard reality of modern life" does everything to prevent that at times.
Valentines day in that case is more so an excuse like a Birthday or anniversary to just go out and do something like have a meal, go somewhere nice or special to the pair of you, or just buy that thing they've been wanting but you've not been able to justify 'wasting' money on. Stuff you want to do but struggle to find 'when' or "at what cost?", give them a day or gift that's extra special, or if time is still an issue
(not everybody can get days off) then just buying or making something to show you're still willing to put the time and thought into doing something a bit special even if its just a cheap card with a thing they like on it
(or hand made, extra special, no corporations profiting here, no excuse). It's one giant excuse for you to be able to do those things, a free pass that allows the two of you to push other commitments and costs aside
(to a degree) and let you do things you can't always do, all with no questions asked "because Valentines day, that's why".
Speaking of anniversaries, there's another holiday that benefits companies more so than anybody else, but when that date rolls around I'm not going to pop on my finest edgy fedora before whispering "we're not doing anything special today" into her ear to preface a speech on consumerism. "Peer pressured into doing things" or "making an effort" aren't words that should really be getting used when talking about doing nice things with or for your partner, people should be jumping at every opportunity they get to do these things...Yet here we are.
Yea, it's yet another holiday which exists these days primarily to fill the pockets of companies...But so what? I'll take any excuse to do something different and more 'significant' than regular days with my s/o because we don't have the time and/or money to do these things as much as we want to. I should hope everybodys s/o knows they love them, but these days in a lot of circumstances it can sometimes be difficult to show just how much all day every day. Well, here's the corporations providing one big excuse to do these things, and it seems backwards for people to be looking a gift horse in the mouth.
