Always the one up ahead...so 2010-2020.
The one we are in now I call the O!-Oh's ! !
O-Oh-One, O-Oh-Two, etc.... they can't be X - they can't ask Y - they can't be lost
- because ALL of those imply a quantity or a reason or a something to loose...the poor unfortunates have nothing to subtract from nothing....(not even a backbone or navel to do a belly rub.)
