DS (6.5) asked me, 'When exactly should you use a semi-colon, because I see them all the time?'
Dismissing the idea that he sounded like the little boy in The Sixth Sense (I see semi-colons... all the time.') I gave a vague explanation and then furtively googled semi-colon usage. The next day I carefully explained it to him, whereupon he said, 'I know - I asked my teacher.'
Does he have the makings of a good pedant, do you think? Oh, I would be so proud! Imagine the Georgian family annual newsletter: which we don't do This year, Mini Georgian mastered the art of the semi-colon; we have had a high old time finding him examples to correct!
Ha-ha!
