It's Not Always About You

One of my friends gave me a shirt that says "I Don't Know What I Would Do Without You but I Bet It's Awesome."  I was wearing the shirt one day last week and the wife happened to look at it.  Her response was "What's that supposed to mean?  You got problem with me?"  I replied back to her, "Who said the shirt was even talking about you?  You ASSUMED it was about you and just made an ass of yourself in the process."  I need her to understand my world does not revolve around her.
