Girls can spend more money on shit than us. Once they start buying designer clothes, shoes and bags it is over. You buy a new tv every 10 years and they cost 1-2,000 usually depending on your budget. You can spend 2k on just 2 outfits at Bloomingdales. And that doesn't even include the insanity that is jewelry or furniture.Easier to apologize than to aske permission. Bedrock of a stable marriage.
I would be careful before starting a game of look what I bought without talking about it with your wife.
Much easier to have one of your friends or even better friends gf/wife come over and tell your wife what total garbage your tv is. Preferably from a woman she does not like. I guarantee you that your wife will want to buy you a 70" monster HDTV within a week!
