ELI5: Explain Like I'm 5

Bridle

A bridle is like a special set of reins that go on a horse's head so you can control where they go when you ride them. Imagine the bridle like a set of special harnesses that help you steer the horse or make them stop when you want them to. The bridle has a few parts, like the bit which is a special metal piece that goes in their mouth and the reins which are like strings that you hold onto to control where the horse goes. The bridle is really important because it helps you communicate with your horse and keep them safe while you ride.
