Turned out that our friends were bringing their kids, and they were intending to stay with us. Which of course delighted us -- we really like these people -- but also caused a couple of logistical problems.
There is a joke about a person whose home was in danger of being flooded during a storm. The police come and say that he should leave; he says no, I'm a religious person, and I know that god will save me. The firemen come, the Coast Guard helicopter comes, the water gets higher and higher, his response is the same. He drowns. Facing god, he says I was a religious man, why didn't you save me? And god replies I sent the police, the firemen, the helicopter.....why didn't you leave?
I am not a religious person. But the ballgame in Baltimore would have caused us logistical problems -- seats in separate areas, not obvious how to connect up, and, of course, the thunderstorm predicted to arrive around the middle of the game. Instead, a ferocious storm arrived hours before, and the game was rained out. Massive solution to a personal problem. Problem went away.
