ipad caricature of MISS GRUNDY from the RIVERDALE project

I remember reading the comic,"little Archie" as a kid, and remember that all the gang were taught, as younger, by Miss Grundy. She was OLD THEN...
Fast forward to the teenage years at Riverdale, and the gang is STILL being taught by Old Miss Grundy.
How IS That?.
Maybe a better name for her should be Miss Gang green. We know NOTHING about this character other tha her designation is "teacher" and it's all she gets to be.
I remember when I was a kid in elementary school how I thought on some level, that teachers weren't "really real." They were that special class of Beings who remained frozen in their designated area until the next day when you would see them again, trying to teach the same thing. It's funny how we assign categories to people forgetting that there's a real man behind that police badge, or girl behind that cash register, or woman who holds chalk in front of a blackboard.
Grundy is a mystery. Who is her family? Where does she live? What does she do on the weekend? What is up with that polka dot dress she is always in?
I see Grundy as a sad character locked into a profession she's poured her life into...unappreciated, un noticed, and now too old to do anything else but wait for death...that doesn't seem to come
