They also have the annoying habit of pushing concrete out of their way as they grow, and not just sidewalks. At my house we developed a water leak because the main waterline was 1 foot away from a tree. I don't know which came first, the tree or the waterline, but surely someone realized they were too close together, but they put them there anyway. Fast forward 50-100 years and the tree roots got bigger and ripped up the line.
