A large tree grows near my house, but on my neighbor's lot. For some time the lower branches on one side have reached over to my house. I've wondered about the damage that could happen when the branches bash against my house in a gale, and about the squirrels climbing onto my roof and into my attic. All those worries. Then, yesterday, I noticed the the squirrels have taken to trotting down the offending branches and ripping off the bark to line their nests. This kills the branches, which will soon drop off and so -- no more branch problems and no more squirrel fears. Worry is so unproductive, isn't it?
