If, for whatever reason, you and your wife discuss which of your friends you should marry should your spouse die: don't!
But if you do - don't pick the friend who's company you actually enjoy and think is an interesting person. Always, always, always, pick your best looking friend. Yes, it shows you are superficial and immature, that is - you are a guy. That's fine, your wife expects this - it is safe. Attempting to show that you've entered adulthood will only hurt you.
In the game of life, good looks are a lucky hand. Good if you've got them, but not really indicative of anything important. Your wife can deal with this.
But enjoying another woman's company as a person - that is a threat, a danger. That is what she thinks (and hopefully does) have with you.
In short, it is counter-intuitive, but on this one - be a dope.
