Short Answer: Because they were "boo"sy doing ghostly things! 👻
Explanation: The ghost couldn’t see his parents because they were so busy being spooky and doing ghostly activities. They were probably busy scaring people or floating through walls, leaving the poor little ghost all alone. But hey, at least they were having a hauntingly good time! 😄👻
