Last year during a show-and-tell time (which I don't do often, I must say...perhaps this is the reason), one of my little girls brought a single bird feather. I said, "Okay, A, please tell us about your feather."
"Well," she said, "This feather is from my pet bird."
"Very cool! Tell us a little about your pet bird, then."
"My dog ate it and this feather is all we have left."
Of course, my little darlings were MORTIFIED...all the while their teacher was trying her very best to not end up crying from laughing so hard.
