This one is simple: Historically, if you've succumbed to you're wife's wishes and given her something she really wants, she's given you a kiss on your cheek. One morning, during your commute to work (you commute with your wife), the two of you discuss an upcoming renovation and the two of you have differing opinions on the type of tile to use in a shower. With 10 minutes to go before you drop her off, you ask her one more time, "Are we definitely going to go with subway tiles?" She says, "I really like them." You leave the conversation as it is, you don't say another word, you just continue the remaining 10 minutes down the road listening to the radio. You get to her building, stop, and as the two of you lean close for your daily kiss-before-work, you smirk and turn and your head to side presenting your cheek to her. Simple question - did you just insult her?
