Pulling out some hairs
Some of the things that kids do are rather strange. That’s because they lack knowledge in a variety of areas. If a kid has just observed their mother’s legs, they might not understand why a guy would have hair-covered legs.
We’re guessing that this kid had a similar experience. He was perplexed by the hairy leg he saw on the airplane, so he pulled the hair out right away. Fortunately, the guy didn’t get angry. He only took a photo to share later with his friends.
