I have serious problems with a number of contractions that don't seem to be recognized as such.
There are other "similar-sounding" words, too. For instance... there & their... affect & effect... to, too, & two... then & than... where & were...weather & whether... and, I could fill half a page if I were to keep going. I really don't understand it. Didn't all there guys and gals go to the same public schools I attended....... And, I failed 7th, failed 8th, failed 9th... and finally quit during my second try at 9th.
I'm just being honest about this. Almost everyone on these forums is better educated than I am (although I DID finally go back to school), yet they don't seem to be able to compose even some of the simplest sentences, and often seem to have never heard of basic punctuation, nor learned what a paragraph is designed to do.
