Typically I handle my FILs' shenanigans with ease, but I'm at a loss for words...*scratches head* A few weeks ago, I took DS to see the FILs (FI stayed home that weekend, so it was just DS and I). We were at dinner with the whole family (FI's siblings, parents, grandparents and his uncle were all there) and discussing wedding plans (full disclosure: his parents are chipping in), and the conversation ultimately turned towards the importance of considering the amount of money spent vs. the amount of money received, and how "you always want to end up coming out ahead."
Me: Wait, what?
FFIL: Yeah, like a business transaction, you want to make sure you make more than you spend. (*everyone around him nods in agreement*)
Me: I'm confused...I'm sorry... what?
FMIL then stepped up to the plate and explained that "you know, it just makes sense" that you'd want to make money from the wedding. She also mentioned that they keep tabs on all gifts they receive, so they know how much to give for related events, and that I "should start doing that too, it makes things so much easier." (Side note: I remember when DS was christened, FMIL asked me to make a list of who gave money from their side, and how much was given from each person... now it makes sense why she needed this valuable information). I replied that when each of my sisters got married I don't think we really paid much attention to how much they received from their guests, aside from just noting that they gave money for the purpose of thank you notes.
FMIL: Yeah, well we pay attention (laughs)
I ended up switching the topic, mainly because I couldn't figure out if we were all on the same planet, but went home the next day and mentioned it to FI. His response was "well yeah, it makes sense right? I mean who wouldn't want to make a profit?"
Me: WHAT?

We talked about this, and I told FI it seems rude (and honestly, a little slimy) to think of a wedding as an opportunity to make money. I don't know if it has to do with our different backgrounds (my family is blue collar/rural, his family works on Wall Street-- not to imply that everyone working on Wall Street would be rude like this, but I feel like there may be some sort of socioeconomic differences coming into play here). He ultimately saw where I was coming from, but also seemed to still agree with the whole idea of trying to profit from the wedding, which should make for some entertaining conversations now (to say the least).
So yeah... is there anyone who can explain this theory of profiting from the wedding to me? And how far would you let FILs go with this? Talking about it at a dinner table is one thing, but if FMIL wants another list should I oblige? Just wondering how to play this hand...
