If you’re looking for a rational argument for the big party or the religious ceremony or anything like that – You won’t find it. These things are meant to play to the emotional, and this isn’t a flaw, it’s the whole point. People really need to embrace that we are, in fact, very emotional creatures, and that this is not a bad thing, and that yes, a lot of the things we do are done just for the emotional satisfaction of it. Because it’s fun, because it will make you or someone you care about happy.
If neither you nor your partner give two shits about big parties or ceremonies, then neither of you needs to bother. If said partner does want this and you don’t, then y’know, maybe have a good chat about that and find a compromise. That’s how partnerships work. (Me personally I’d love to organise my own wedding and go all quirky with it, but I can live without it)
Being legally married is a separate thing, and is inexpensive in most countries (just a small fee so the bureaucrats can process the bureaucracy), and at least in my country is often done weeks if not months in advance of the big party and/or religious ceremony, with the couple already being legally married while they organise their wedding stuff. To be legally married is to have you and your partner recognised by The State ™ as being a family unit. This has uses for a few situations in life.
612 years in the past
In Brazil. So almost a century before the first europeans landed here. I’m assuming I just plop exactly in my relative earth-location, but in the distant past. (… It would be really funny if this was overly literal, because I’m currently in the 12th floor, so I’d thanos snap into the past and immediately fall to my death)
Well
As a person from modern times – From AFTER the Americas came into contact with Europe, if I went near a person here in the Land of Palms (that’s what the natives called Brazil!) from those times we’d both get horribly infected and die a lot due to how antibodies work. Viruses did a lot of the legwork in genociding the natives. Euros would deliberately do things to infect natives so they’d die of illness.
The place I currently live in is slowly turning into a desert, but was a deep jungle back then (… It was still a deep jungle in the 1910s tbqh).
… I think I’d just die? Become food for a jaguar or eat a poisonous fungus or sth.
Would love to indulge in the fantasy of giving the Guarani people guns and a warning to shoot white people on sight just to see how history would change, but that ain’t happening.
