My wife says I just love to collect stuff, but I reply that:
I spend little on my hair (she cuts my hair while she goes to one of the most expensive hair salons on a regular basis).
I spend zero on colone and aftershave (she buys all sorts of fancy scents, me I hate using anything with scent).
I spend nothing on skin care products except my electric razor (but she buys Nivea and an assortment of overpriced goops).
I spend little on clothes and shoes (but she goes to up-scale boutiques while I am fine with the usual department store stuff).
I spend little on eye-wear except cheap reading glasses (but she buys designer frames and requires both prescription glasses and contacts).
I spend noting on fancy unmentionables (but she has a nice collection).
I spend nothing on makeup (but she likes the expressive stuff).
My vehicles costs are half of hers as she runs all about town with various mothers, or drives around looking at stuff, or goes to myriad shops for whatever; whereas I just do internet research and then mail-order to the front door.
Any-who I do not begrudge her indulgences, but I realize my purchases of cameras, computer gear, calculators, music gear etc are much in keeping with her costs.
