A. You basically have two options
agreeing with your wife:
1. You give in immediately. That is often misconstrued as
"You didn't even listen to what I asked!" or
"So it doesn't even interest you!"2. You feign counter-arguments, but eventually give in. That bears the risk of reprimands along the lines of
"Why do you always have to argue?" or
"Is it so hard to agree with me right from the start?" Plus the notorious:
"We always seem to disagree about things."
B. There are
no really workable options of
disagreeing with your wife, it's all theoretic.
