If I had to choose? Srsly?
Finesse' the situation. My wife of 30+ years was deep in menopause. (For the hetero noobs out there, it can be VERY dangerous).
I wanted a new bike, she wanted to watch the money. I picked out the bike, she went into the sales manager's office without me to 'negotiate' the price and terms. I watched through the window as she started having hot flashes and peevishness points. I knew what was coming.
After twenty minutes the sales manager stood up and pointed his finger at my wife. HUGE mistake. After another twenty minutes the sales manager came out to find me in the accessories department and said "You can have it at cost and I'll throw in a helmet if you just get her out of my office. Please."
If I had to choose between a bike and my wife. No contest. My wife, hands down. The entertainment factor grows and never ends. 'Sides, she still brags to her friends about the deal she got for me.
