Dh never says a word about what I buy. He learned about 30 years ago not to say anything. We use to visit my parents and would go shopping at a craft store. I would only buy little cross-stitch kits that were on sale. This is basically how our conversation went that day:
Dh: Do you really need that?
Me: No, but I want it, it's cute.
Dh: Don't you have enough stuff at home?
Me: Probably. Do I go out to Bingo with the ladies, then go sit in the bar with them for a couple of hours afterwards?
Dh: No.
Me: Do I go bowling with the girls and sit in the bar for a couple of hours?
Dh: No.
Me: Where am I every night?
Dh: Home.
Me: What am I doing every night?
Dh: I don't know, some kind of stitching.
Me: Now, would you rather have me home stitching or out with the girls?
Dh: Home. Is there anything else you need?
Me: No, this is it.
Since then, he never says anything about fabric or anything else I buy.
