You know your day is going to go very badly, when you start it by locking yourself out of your apartment. The thought of calling off work and curling into bed while the day passes by seems to be the optimal solution. Optimal of course until you try to open up the door that is locked, which is of course how you got yourself into this predicament.
At least you aern't in your underwear and it's cold. That would just make things worse.
