Did you know horses have friends? They do according to writer Sterry Butcher, who lives on a Texas farm with horses.

According to Butcher, horses form friendships, and these friends stand nose to rump to cooperatively swish flies from the other’s face with their tails. They’ll rake their teeth against the other’s withers or back, scratching places the other cannot reach on his own.

And not only do horses scratch each other’s back. They watch each other’s back. In the wild, they spend the entirety of their lives within the eyesight of another horse. Even domestic horses, who don’t venture beyond their pasture, will take turns staying awake while others sleep. It’s like shifts on guard duty.

What horses have is what we need. Every one of us needs a friend. Someone who will swish away the annoying biting flies that come toward us in life. Someone who will scratch our back, helping us with the things we can’t reach or do on our own. Someone who will stay awake and protect us from dangers.
