I could be writting alot of usefull code, but instead we are both stuck reading this comment. Hope your happy now. I am not stopping before you are! Wonder if anyone is still reading. Not like anything usefull is coming later. Wonder how many skipped the first part. Please just go on with your day / night. THIS AINT OVER TO I SAY IT'S OVER!
