All vacations must end, and on our last day in Morelia our depression was intensified when the very pleasant security people of the local airport (as opposed to the almost all surly Americans) told Rosemary that she could not board the plane with her Chocolate Carlos V bars (they instructed her to put them into the luggage) as they could possibly be plastique and explosive that is a phenol derivative from aspirin. Our depression lifted when we drove into Canada Customs at Blaine. While Mexico might have friendly people and ancient church doors where I can pose Rebecca, I like the "almost certainty" of Canadian life. I like the steady 110 volts and the unwavering 60 cycles; I don't fear cops, and most of us have to pay taxes. As soon as we were in Canada we wondered what the unpredictable Lauren (Rebecca's 4-year-old sister) would say upon seeing her sister back. Lauren said, "I missed you," and gave Rebecca a hug and a kiss. It's nice to be back in Canada.
