Funny business. Bachelors, they are young stallions, who have aged out of their birth bands, and are learning to find their place and hierarchy in life.
You can often find them running, sparring and causing some kind of ruckus all over the forest. They are fun to watch because even while they have many disagreements, they are not malicious, mean spirited, and they don’t hold any grudges.
In other words, they know how to agree to disagree and then be friends again 5 minutes later. Don’t you wish sometimes that people could be more like that? Oh the things we can learn from wild horses.
