I used to live in a slaughterhouse district where the damn things would crawl out of sink, bidet and shower plugs, making every single trip to the bathroom a very anxiety ridden experience. Plus they were of the flying variety, and occasionally, of the albino variety.
I personally hate them and I relish on the fact I live somewhere where they're not that prominent, but I do recognize they're as essential as any other insect and a potential food source.
