One of the things that originally attracted me to this board was the opportunity to hone my written communication skill. I do not know if I have made much progress. I do recall "back in the day" an ungrammatical usage or a misspelled word would get you noticed and dismissed as not a serious person.
Maybe all those people got the zot.
I think “back in the day” has replaced “when I was young” for the boomers. They refuse to admit they are no longer young. OK right? :)
