As I was buying a new ruler for a project, my DH remarked "why do you need a new ruler, an inch is an inch?" To which I replied, "why do you have 40 different screw drivers to screw a screw, a screw is a screw?" To which the saleslady laughed out loud. I don't make comments about his Miata which only gets driven on nice cool days (we live in ETexas!)
I must be fair, however, he usually just lets me get whatever I want and doesn't make me justify it. I wonder if it is because he doesn't dare? I have worked since I was 17, through pregnancies, child raising, moving household(for his job), illness and everything else. Just did it. Now I am retired and while he sits and reads, I quilt. If I cook, he eats, if not, he scavenges. If I clean, he doesn't notice and if I don't ditto. So we are okay. Just don't let your DH's comments get you. Get what you need and quilt on!
