When a person dies, everyone grieves. Family, friends, co-workers--people mourn the loss of a loved one.
But we often forget that animals, too, have the ability to experience grief.
When Wagner de Lime Figueiredo died, his brother brought his horse, Sereno, to the funeral.
It was a sad service, but the most touching moment was when Sereno laid its head on the coffin and whined and sighed, as though the horse was also mourning.
You need to see this emotional video of a horse saying goodbye to its owner. I've never seen anything like it.
