Manitoba... Not sure what to do about them. Restock the province with megafauna and encourage tourism, I think. How quickly can we breed back the saber-toothed cats?

Romeo and Juliet *died*. I always liked that in a teen romance story.

The sharp side of the knife goes away from you. Pure reason does not trump brute force but suprisingly few people know what hot peppers look like when the teacher asks if you have enough to share with everyone. Never take the lid of a pressure cooker 'to see if it's done yet'. Even if you are careful with the picric acid that won't matter if you are careless with other items next to it. Move *away* from mysterious burglar alarms. Do not append 'you moron' to exposition directed at people who have just broken into your building. 'We need to talk' is overwhelmingly unlikely to precede good news. A rough brick wall may be used to sort socks or as a backdrop for sock-art (The Neglected Art). A silent cat is Up to Something. Lungs are unsuited for many possible atmospheres, including that of London, and anything with a high content of industrial cleaners. Youth will not save you from Newton's Laws. Or Darwin's.
