Disagree. I am younger than Boomer, no problems with cursive, gotta be A Lot younger than a boomer to not read cursive. Maybe it's regional, but it has been only very recently that schools around here considered dropping cursive, so you'd need to be quite under 20 to have zero training in it. here.
I am also one of those weirdos that enjoyed sentence diagramming. I would have to consult Google if you asked me what a gerund is, tho, as I never knew, and apparently did not need it in life.
I am a two spacer, especially after colons. I also do not go along with Spell Check as it often disagrees with my very fine grade school teachers. simple rule was double the consonant before you add -ing or -ed, etc. so I do not think that canceling is correct, it's cancelling. I am not going traveling, I am going travelling.
Lots of rules I remember and not giving them up. Ok-fine being considered old and will accept when that term changes to ancient. just need a few years to get used to that...
