OK guys this is a tough one to swallow.
As a rule, guys are very proud, so when our wives are right about something it is our instinct to mumble something and walk away without ever truly acknowledging that our wives were right.
The funny thing is that we are trying to be proud at the expense of the one person in our lives that is not going to attack us if we are open and vulnerable with them.
Sure my wife may gloat, and ask me to repeat that she was right a few times. But if you do it with good humor, you just might get a reward that can relegate the discomfort of your damaged ego to an afterthought.
