Non veni pacem mittere, sed gladium.
When you're little, geese can be terrifying. I remember being that age and chased by them. When I got a bit older, I brought a stick and whacked them, but the first time they come at you when you believed all this time that they were nice is startling.
They have a wicked scary hiss sound they make. And they have teeth. I was an adult before I got close enough to a goose to see its teeth. They are nasty birds.They do make great "guard" geese!
When I was 4, I was attacked by one of my Granny's geese, fell on a pile of old steel roofing, and cut myself bad enough to need stitches. Well, Granny fixed that by teaching me the old "grab them by the neck" trick and before long, they RAN when they save me coming!
