Consider Exhibit A:

You: "I walked into work today and before I could get to my desk, I saw Tanya walking over to the coffee machine and wouldn't you know that heiffa had on the same shirt as me?"

Your girlfriend: "You better stop it. Which one?"
You: "The blue one—you know, the one with the orange flower print? I got it from that store across town? On sale?"

Your girlfriend: "You mean the one you found on the $29.99 rack in the back? The same day I found those shoes at the store just down the street?"

You: "That's the one! I wore that shirt to work a few weeks ago and she complimented me on it and next thing I know, she ran to the store and bought my shirt and is wearing it to work! Can you believe it? Do you know how that made me feel?"

Your girlfriend: "Aw, hell to the nah. Are you serious? That's horrible. She's got some nerve . . ."

For sure, this conversation could go on for hours, morphing into all kinds of side conversations that have absolutely nothing to do with the issue at hand: that some woman was wearing the same blouse as you on the same day in the same office.
