I never understood how she could spend so much money on special shampoo and conditioner. It irritated me every time she came home with another bag of expensive stuff and I'd point out that there was perfectly good products at the drug store for a 1/4 of the price.
Well, when we split up, she left several fancy bottles in the shower. When I ran out of my cheap shampoo, I figured I'd use up the expensive stuff rather than just let it go to waste.
You probably already know where this is going. Yep, I now buy HER brand of shampoo AND conditioner and have to make special trips to get it since they don't carry it at the drug store. I guess I owe her an apology but that's not going to happen.
