SHANE MILLER SLEEP DIARY: Went to bed at: Late. How long it took to fall asleep: Forever. I have insomnia. Duh. Number of caffeinated beverages you had consumed: Zero. Thanks for advising me to quit! My stress level is off the charts. I can't sleep right on a normal day, and lately my days are filled with the best kind of chaos. My ex-wife and husband number two are filming in Poland for three months, so I'm turning down movie parts to focus on the most important role of my life- impossibly charming and somewhat capable young single dad. My son won't stop asking questions. My daughter won't brush her teeth unless I sing her showtunes. Our regular nanny quit. The only person I could trust to hire as a temp nanny is my best friend's sister. If Mary Poppins and Bill Murray had a baby it would be Willa. Fresh out of grad school and beautifully weird. She hates my movies, and my kids adore her. I couldn't sleep last night because she wasn't here. Turns out I can't sleep unless she's in my house now. Turns out she's what's been missing from my life all along. If my friend had any idea what I want to do to his gorgeous troublemaker of a sister, he would smother me with a pillow. The chances of us succeeding as a couple are about as good as that little indie movie that I made being a huge hit. But it's a chance I'm going to take.
