The last topic in the textbook this semester is Yellow Dust. Obviously, the kids already know about Yellow Dust and how annoying it is (though this year wasn't so bad), so I can't really blow their minds with any new information on it. Plus, on YouTube, the top hits for Yellow Dust are all foreigner vloggers which is a whole bunch of self-absorbed navel-gazing I don't want to encourage. Apparently, Yellow Dust makes colds worse. In other news, the Pope is Catholic and the sky is blue.
