Went for dinner with some colleagues yesterday. One of them suddenly steered the conversation onto chemtrails and then spent ten minutes holding court about how they're caused by governments dropping chemicals to change the weather, how they've used this power for good as well as bad (apparently they were able to cause a hurricane to deviate path and miss Hawaii), and how it's not a conspiracy theory because it's proven with easily available facts if you're just willing to open your mind. Little bit awkward, but amusing to watch my boss's face as he listened and realised that it was on him for hiring this guy....
