Yeah, the old toilet training, and all the stuff that goes with it; many times I remember scraping out the nappies, listening to the Sunday night Coodabeens. What I've found (I think my wife would agree) is that it goes SO FAST. Doesn't seem like it when you're living through those days of totally dependent Little Persons, messes at the worst possible times and no sleep, but it's gone in a flash, and now I have two teenaged sons, both of 'em drummers (and good ones) and they barely seem to need me at all except for money and transport...you will observe the use of the word 'seem' just there...
You wonder where the time went and you hope you did something good with it.
