Without using years, date yourself.

@DrWatson Hard to believe but my first school used slates, not paper, and some sort of stone stylus to write on them. I think that was also a slim core of thick, bedded slate. I seem to recall bands of lighter & darker color along its length. It had a point but I don't know whether/how it could be resharpened.

My first days at school were miserably bad but that's another subject.
