I make the money, she’s home with the kids. Our choice together. So although in theory it’s my money to spend as I see fit, in reality the CFO will object if she detects unusual or erroneous expenditures. Which means guns are purchased creatively. I’m a responsible sort and mostly make sure the household obligations come first, but the reality is, my wife is the queen of frugality so she undoubtedly has the moral high ground. She’d have no problem whatsoever with how I spend my allowance of, you know, about $50 per month. On that budget it’s hard to buy guns so I tend to buy them at work where I can have it deducted quiet-like from my paycheck, or alternatively I put them on the family credit card, which is where most of our household spending goes. (We pay it off in full every month.) She keeps the bank account ledger and I keep the CC ledger, so this works.
The reality is, my wife really, truly doesn’t object to my hobby, she just doesn’t want to see the reality of money leaving the bank account for the purpose. She knows it happens, but is happy not to press for details.
