Hey Edward, the correct word is "lack" not "lock". Also, when referring to people, "there" isn't used. The correct term would be "their", in that context. Wait, more mistakes by the educated Edward. "Your self" is one word. Another thing, "deferent" is spelled "different." When you are trying to post something about being educated, you should make sure you are educated yourself and not make spelling errors in every sentence. Just a tip.
