Teachers of this day are not the same as teachers who taught in the 50s and 60s, in my opinion. Teachers from earlier years devoted their lives to teach and were respected in the community. Teachers in these times merely paid a college to get a teaching certificate. I have known teachers who began teaching in the 80s and 90s who could not spell, could not teach capitalization nor punctuation, and other things. These days, teachers molest students, proclaim to to be in love with teen students, so nothing a present day teacher does surprises me. They pay to have a job, once they get tenure, they think they can do anything.
That is my opinion.
If I misspell or use words out of context, the Kindle did it. Not me.
