My MIL is a nosy busybody who loves to snoop when given the opportunity. Needless to say, she's not usually allowed in my home.
DH had a bit of a DuH moment this week and let her come over to visit while I was out working. I'd been organizing and filing receipts and other paperwork that morning, and had left them out on the table. Of course MIL went through them and then had to give her unwanted opinion on our purchases.
From what DH told me, she's "deeply concerned" that I'm out spending so much of his hard-earned money on such silly little things. And I eat way too much fast food, so it's no wonder I'm still so fat when YDD is already 9 months old. She doesn't understand why I shop at so many different grocery stores throughout the week when I should be making a huge list and buying everything at once. Oh, and I need to stop making frequent trips to a couple of cities that are about 40 miles away from us because gas is too expensive to waste like that when we have the same stores here.
DH laughed at her, told her that it's none of her business and I can spend my money however I see fit, and ended the visit. He told me what happened when I got home and apologized because she'd screwed up my organization. Whatever, it took me like ten minutes to get them straightened out and put away.
I can't even be mad at her, because it's so ridiculous. What MIL doesn't know (and will never know, because she can't keep her mouth shut) is that I'm a mystery shopper. Those receipts were from purchases I made while working, and most of it was 100% reimbursed by the companies I shop for. I occasionally travel to other areas when I can group shops and/or get bonuses to cover expenses. Big deal. Even if I wasn't getting paid for it, it's none of her damn business.
How do I tactfully deal with her if she brings it up to me? Should I just BH? I'm tempted to ask her some intrusively personal question but I know I shouldn't stoop to her level. I'm not even sure it's going to come up, since I don't have much to do with her.
