DO ENGLISH TEACHERS HAVE A SENSE OF HUMOR

DID YOU EVER DANGLE A PARTICIPLE? I could have named this post a number of things. It also probably should be split into two or three posts. But I named it like I did, and it will cover a few things English, so bare, uh bear with me and we will see what comes out.
I was not a strait, I mean straight A student. Heck, I was rarely a A student in any thing. And if I ever knew what a dangling participle was, I have forgotten, but I do know that I never did actually learn how to correctly diagram a sentence. Or even understand the reason for doing so. I read a lot. I mean really a lot. I have yet to see a sentence in a book that is diagrammed. I did learn something about subjects and predicaments, I mean predicate's, noun and professional nouns, more commonly know as pro nouns, verbs and advertising verbs, or adverbs for short, and prepositions and propositions. I didn't always understand all them thar things, but we durn sure studied them. But I did learn a few things about using the English language, proper spelling of, and usage of, words like bare and bear, their and there, and others of their ilk. And when to use them and why they were spelled different. I also learned when to use and not to use a preposition. I don't remember all the rules that apply to this English rule, but one of the most over used prepositions in the world where I live and work is the word AT. Usually used in a question. Where are you at? Where are you parked at? Where would you like to meet me at? Drives me up a wall. Or would if I knew where the wall was at. And it was actually possible to be driven up a wall. Well, you get the point. I hope.
Now, how does an English teacher of today teach English. Like, you know, really teach, you know, English. If their, uh, there is any word or phrase, more over used than the preposition at, it is the words like and you know. Drives me down the other side of the wall. Know what I mean. Feel free to correct my incorrectness.
Guess I better end this post and get my tongue out of my cheek before I chew it off. And That's The View From The Ditch Bank.
