You show them the navy pinstriped pants you picked up at Banana Republic on the extracurricular 45-minute outlet mall sprint the three of you enjoyed during the drive from San Antonio to Austin (by the way, best outlet mall EVER!) and they say, "Don't you already have a pair of blue pinstripe Banana Republic pants? I thought I had seen those." And you say, "No, you're thinking of my navy pinstripe Banana Republic blazer." And they say, "Oh yeah, that's right."
(No, I am not getting kickbacks from BR for this post. But I should, dammit.)
