Please consider learning the difference between the following words. They're (they are) Their (they posses something) There ( as in "there was a frog family sitting on their little lily pad and they're really cute." or "their sailboat is over there, in the harbor. They're planning on sailing to their summer house at noon.") Your car (you posses it - it's yours) You're (you are) "You're going to your colonoscopy appointment this afternoon, aren't you?" Would HAVE - not would OF ("I would have given one hundred dollars to be able to read some of the comments without developing a massive headache") Would've = Would have. There is no such thing as WOULD OF. It doesn't exist in the English language. "Would of" literally has no meaning. Please Don't type it. Should've = Should have. There is no term "should OF" in the English language. Don't use it. It doesn't mean anything. Sorry to be such a *****y person right now but I seriously have a headache from trying to decipher some of the comments and it's unfortunate.
