I feel a ramping up of these things too. Not that I’m against parties. If a friend of mine invites me to his super italo disco '80 party, or the wild boar bbq party, I’m all of it, but what puzzles me is that some events have to be a big thing.
Like the promise of marriage parties. Promise of marriage is a thing but until some year ago was an obscure law, that basically stated that if the groom or the the bride changed mind about marriage or after six months the marriage isn’t done, the betrothed have to give back the gift and pay the expenses and damages to the other.
Now the promises of marriages are big parties with dinners, photo sets and so on, like an actual marriage.
