When you are making your own detergent with borax, baking soda, "natural" (most likely handmade, organic and therefore, expensive) soap and (again, expensive) essential oils, you are not being thrifty. You are showing off. You are saying, "Look at what a good, virtuous mom I am, I even make my own detergent!" If you were really serious about saving money, you'd drive over to the dollar store and buy the biggest box of off-brand you could find because, seriously honey, it's all just soap.
Pinching pennies to these moms seems to be having to drink "just plain old store milk," bagging their own groceries, and eating leftovers. They think stockpiling Froot Loops and Coco Puffs is frugal. (Have they never heard of bulk oatmeal?)
I'm having a difficult time pitying these women. *
*I am also tired and crabby as hell. And yes, RobertaX, I am totally copying your footnotes. I hope you don't mind.
