I got five hours of sleep last night.

At 8:45 this morning, first phone call of the day, the woman I was talking to commented that I must've had my coffee this morning, because I sounded cheerful and optimistic. *blink* (I don't drink coffee generally and hadn't had any today. And I got five hours of sleep last night)

And just now (almost 4:00), I had a different woman tell me that she liked working with me better than the guys, as I made things seem easier to understand than they did. *blink*
