Things that people think are true, but maybe aren't....

I'll start. When a person catches a 12 inch bass with a gash in it, I often hear, "WHOA! Something really big must have tried to eat that thing..." and they look as if they are holding a fish that just went through something pretty traumatic and that there is a HUGE fish probably in the same waters. 

Ok, maybe it's true. But......it's also possible that it's a sore, or a scratch mark, a scar from a long time ago, or something else....
