Dear Zeus and Isis,
I know how you both get very upset when I leave, but try to keep your spirits up while I'm gone. It's not the end of the world, you will still get fed, and I promise your litter box will still be cleaned. If you nap longer during the day, you won't even know I'm gone!
I will try to write you from Pittsburgh. Hopefully, I can have some sort of Internet access to send you e-mail. Remember: Even if you do not hear from me, I still know what you do so BE GOOD.
