Why do some people have the need to correct other people's grammar? Look man, we're all just banging on a keyboard and not writing a letter to the board of directors, and 99% of the time a wrong word use we all knew what they meant to say. I find misspelled, wrong words used, etc all the time in the newspaper, on the internet, on TV, when talking face to face, and I don't run to the phone and call them, or tell them to their face they said a wrong word just to show them how stupid they are and how smart I am. Besides that you didn't offer any help with his question.
Now for a story: When I was 1st grade my teacher asked me which was the correct words to use in this sentence to make it right: "You're going too the store? can I go to?" I said to her: "I ain't knowin the answer!" She looked frustrated and said: "Son, where's your grammar?" I said: "Well she's out in the kitchen baking cookies, where did you think she was?"
