There is something to be said for eight or nine hour days.
On the days that Gabe goes to work, my morning starts around 7am when he leaves. I'm "on duty" until he comes back home, at which point I generally crash and inform him that Jonathan is his son. ;) Anyway, I realized today that always, every day, around 2pm or 3pm I start checking the clock and counting the hours. It is like being at work and knowing that 5pm is getting closer - it gives you a bit of lift just knowing that you're almost done.
But at 2pm, I still have five hours to go.
