Nothing like catching the eye of the guy behind you in line at the grocery store, realizing it's that guy from high school who wasn't hot at the time but suddenly became some sort of hot emo rocker that you know is most likely bad news but you feel might just possibly be at least somewhat solid because, technically, you've known him for over ten years so he can't be totally bad news so maybe you should say hi and.....
...then you realize you're buying a stack of Lean Cuisines and ten thousand cans of cat food. And toilet paper. Oh, let's not forget that.
Nothing like being embarrassed about your groceries.
