He ain't tame. He's ornery as hell.
I don't doubt what you said for one moment. However, that old saying comes from the numerous times in the past, when some farmer has a bull
he may have raised from a calf, and was a "regular pet"...
He always trusted that bull...until one day ..the bull realized he was bigger and stronger than the farmer....
I knew a farmer named Norm, who trusted his bull, until one day...he ended up a parapalegic for the rest of his life..
As a child, my wife lived nearby a farm, where their farmer kept a bull in the pasture. One summer day, the farmer made his way back to his
home, but left his intestines hanging on a barb wire fence. He trusted hjs "tame' bull..
I have personally seen a number of "close calls" with bulls, and must admit that in my younger..and foolish years, have tempted bulls, by imitating
their pawing front feet, and relying up on my own feet to escape to nearby cover..
I say foolishly, because it may have worked toward making a mean bull....and I never was any kind of a track star..
