DoraMarr Thank you. You are quite correct that posters jumped in without any background information but the comments, well, some of them were untoward to say the least.
My granddaughter was unaware that we were enthralled with her reply. She went away with the rightful impression ( no pun intended! ) that it was wrong to bite, or attempt to bite.
I envy Primary School teachers, moulding their little charges as they progress through their formative years, but as for Secondary School teachers, that is another matter! They deserve all the rewards that are available, not that I am saying that Primary School teachers don't.
A very noble profession.
