I've just about always chewed to what others might consider an excess. Never have counted the number of chews, just keep at it until I think it's enough.
That made (or likely would have made), the Assistant Principal of one school I attended quite happy. She would come into the school auditorium, where those who brought their lunch to school had to eat, and tell us to masticate our food thoroughly. It was almost comical, considering we were in auditorium seats which leaned back some, so, we weren't sitting up straight; but, that didn't seem to make no nevermind to her. As long as we masticated we'd be living up to her demands.
Mother on the other hand, didn't chew much...if at all. She cleared a plate before I finished my first bite. That made mealtimes a little tense. On one occasion it took me nearly an hour to finish a hot dog.
