Had Roger got the date correct, the sock drawer would be sorted, and so one morning in the not too distant future you won't have socks to wear and will be late to work, and your grumpiness will affect a co-worker who will go out drinking that night because he "hates himself" and get blind drunk and try to break into a top-secret nuclear bunker, and in dealing with him, someone will inadvertently fall on a button and launch the missiles.
Thanks, Roger - you just started World War III.
