First things first, what exactly is pony life? Well, I'd say it's much like human life. You have your routine, you go through different stages of growth, you make friends, you get into trouble, you learn lessons, etc. But, unlike human beings that are biologically capable of reproduction, ponies can only reproduce with other ponies. They cannot produce offspring with any of the other equines or non-equine animals who share their environment. In addition to this, they do not possess sex organs and are incapable of procreation sexually. So basically, if you don't have a mate, you're stuck being alone.
