A sign from God

A couple of years ago I was leaning on the gate to the amphitheatre paddock and looking at the horses. Back then we still had Tosca and Princess as well as Crownie. I thought to myself "I know that I need to sell at least one of the horses, but I don't know which one". I sighed. "God, can you please give me a sign which horse to sell. But God, don't make it some subtle sign please, because I don't notice those. Can you please make it a really obvious, smack in your face kind of sign. Pretty please."

Then I turned away and went into the big shed. In the meantime, the horses ventured down the hill. Later on I came out of the big shed, with buckets of horse feed. I called the horses, and the herd came galloping up. All except for Princess. Princess was lagging behind, trotting, while a fountain of white liquid was pouring out of her nose. I stared at the horse, stupified. There was my most obvious sign from God. That's the horse I need to sell.
