One thing you should never do
If, while walking home from the bus stop, you come across some unopened packets of Taco Bell hot sauce strewn about the sidewalk, do not pretend to be eight years old for three seconds and smash one with your foot; there is a possibility that the sauce will spurt out the opposite end from which you expected, covering one ankle with spicy condiments. Especially do not do this if you don't have any napkins in your pockets.
