I went on a birdhouse forum and asked how to build a birdhouse and the first guy asked if I had too many cats and went on a rant about getting cats fixed. The next guy rambled on about bird seeds. Yet another post discussed what kind of nail I intend to use on the tree, which led to wether or not to hire an arborist to manage the trees in my yard or try to do it myself. Someone chimed in that their tree had gotten beetles and had to be taken down, which prompted another forum enthusiast to tell us about a storm that blew a tree down on his house. I asked what kind of nails he used on his house, but that greatly offended all of them, so I gave up, never getting any info on building a bird house. I don't have cats or trees, sadly.
