Lol, well said. Accumulating 12 razors over 12 years makes less waves than buying 12 in a month.The issue isn't you buying stuff, it's you suddenly out of nowhere going nuts buying stuff.
That's where the lipstick/shoes argument falls apart too. Yes, they have a lot, but if my wife is representative it happened gradually over the course of years, not in a month or two (although I have no doubt there are exceptions).
