I was at the grocery store and it was pretty crowded. Near the bread shelf, a woman accidentally knocked over a loaf of bread. She immediately picked it up and placed it back on the shelf, accidentally knocking another loaf to the ground. She clearly didn't know that the second loaf had fallen, and so proceeded to walk away. Another person in this cluster along with me looked at me, rolled her eyes, and gave a disgusted look.
What a silly nasty reaction to something that was not only an accident but, let's face it, not all that big a deal.
