"What do people catch in the Queensborough Bridge--bugs?" asked Wilbur.
"No," said Charlotte. "They don't catch anything. They just keep trotting back and forth across the bridge thinking there is something better on the other side. If they'd hang head-down at the top of the thing and wait quietly, maybe something good would come along. But no--with men it's rush, rush, rush, every minute. I'm glad I'm a sedentary spider."
"What does sedentary mean?" asked Wilbur.
"Means I sit still a good part of the time and don't go wandering all over creation. I know a good thing when I see it, and my web is a good thing. I stay put and wait for what comes. Gives me a chance to think."
