Oh my, the ways we can get tangled up! I think perhaps the teacher was the original poster and when she found her student had responded inappropriately, perhaps Dave just deleted the whole thread as a classroom experiment gone bad. I then thought you were being overly sensitive to my chuckle, when in fact you saw that the whole thread had been cleared (which I didn't catch). So easy to misconstrue things online. No ruffled feathers on my part, hopefully not on yours either! Still chuckling...now at myself.
