The "reason why" I turn the sound off most televised sporting events is because many announcers are nearly illiterate, "whethernot" they know it or not. He "should of" "ran" around the end and then he "could of" scored. If it "was" "you and I" out there, we "would of" "ran" the play better... Mrs. Daniel, my English teacher, is surely spinning in her grave.
However, I can see where English would be a real pain if one were learning it as a second language. So many rules, so many sound-alike words, and words that mean different things in different contexts... "It sometimes piques me to peek at a mountain peak."
You might gather that grammar is one of my pet peeves, especially in written form.
There are SO many ways to screw up. There, their, they're....too, to, two...stop me I'm out of control here.
