It’s been a tough work week for me, and I was very happy to drive out to San Francisco airport Thursday afternoon. Our flight was on time, and went without incident, which I am always thankful for. The guy right next to me brought a large pizza on board for dinner. A woman in front of me had her hair dyed in three colors. Hmm, I thought. The two shades of brown look great, but that reddish brown is one color too many. But none of my business, right?
