Loom Knitting at the Zoo

My son is studying primatology in college. This is the study of primates (i.e. monkeys, apes and most importantly his favorite lemurs) . For one of his classes this semester he has to spend at least twenty hours watching his choice of primates (lemurs). Since he is twenty-one and still doesn't have a driver's license (long story involving an accident he was in where he went through a window) he needs a ride to the zoo. So what else can I do while he is watching the lemurs? He snapped this picture of me right outside the primate house at the St. Louis Zoo.
