I don't mean to be overly dramatic, but if the next two weeks are like the last two weeks (arrive at 8am, leave at midnight, 7 days a week), I am probably going to walk into* traffic.
Even the happiest person in the world has a limit, and we are currently well past it. Passed it? I'm so tired I don't even care.
