Now, I don't view this as an excuse to not learn the proper grammar of the day, but just remember that language is not static. It is ever evolving and that the rules that were used just a generation or two ago may not apply in this day and age. Someday everyone may properly use words or forms that in this time seem to be slang or poor grammar and today's rules may seem impossibly stiff and formal.... (my husband's great aunt was a school teacher and her grammar book still had all the rules and conjugations for thee and thou)
