This is funny, and I just had deja vu regarding a somewhat similar situation. This goes back years, and I'll never forget the (light-hearted) argument my parents had over my mother's glee at shopping a sale. Mom: "Everything was marked down and I saved all this money!" Dad: "But you spent money, so how did you save money if you spent money? That's just not logical." And so on . . . an endless circular argument between the two of them, about each one's specific definition of "saving" money!

P.S.: I take after my mom!!!
