How do you know that little cross thingie is either an anyaru or a mamumamu when there is no shit and no babies being born?
Hard to tell, sometimes mamu mamu isn't a cross but a line that hides when not used, sometimes there is a mamu mamu, pee hole nad anyaru, sometimes there is a mamu mamu and a anyaru/pee hole.
Overall the best policy is to think that it's an anyaru until proven otherwise.
