There was the time he fell "headfirst on a marble floor" and got a concussion, the day someone stole the family car ("my dad had to chase it down the block"), or the morning he found a black bat (the furry kind) in the house.<p>But Francis looks puzzled when his mom, Joanne Csedrik, asks him about a family trip to the Philippines when he was 3. "It was to celebrate someone's birthday," she tells him. "We took a long plane ride, two boat trips," she adds.

I'm Ari Shapiro. The 2013 Atlantic hurricane season ends tomorrow. It'll be remembered as one of the quietest on record. Since June, there have been just two hurricanes, both were relatively weak. As NPR's Jon Hamilton reports, forecasters were expecting something very different.<p>JON HAMILTON, BYLINE: The National Oceanic and Atmospheric Administration told Americans to expect an unusually active year with between seven and 11 hurricanes.
