Today is the first day of the rest of your life.
Yesterday is the last day of the whatever the opposite of the rest of your life is.
The day before yesterday is the beginning of the end.
The day before that is the end of the beginning.
The day before that is Wednesday.
Tomorrow is the next day of the rest of your life.
The day after tomorrow is a really bad movie. Presumably. I haven't seen it.
And then we're back to Wednesday again.
