Another zoo story (although not really life-threatening).
I noticed two men with a few small children (obviously, Dads out for the day). The kids saw some Canada Geese up ahead, and ran towards them, arms outstretched, clearly thinking these were for petting. The dads watched calmly, with a beatific smile.
Yeah, Canada Geese are not cuddly. Suddenly, screams and toddlers returning in great haste, with dads having to suddenly switch from "Ah, adorable!" to "rescue the offspring!" mode.
