My brother-in-law is getting married. My husband told me we might have to pay to cover his two high school-age brothers (i.e. their share of the AirBnB, dinner, etc.). I said his brothers should pay their share, one is 18. Eight weeks before the wedding, he explained that we expect them to pay their share or at least try to contribute and we’d cover the rest. We talked through options like getting odd jobs. They did nothing. They are on summer break, have never worked, and just play video games at home. Now, after the party, they say they’re broke and we have to pay. Father-in-law called and told us he doesn’t allow them to work, it’s not fair to financially burden them like this, don’t talk to them about it again, you can pay it or we (the parents) can pay it
