As a kid, the holidays are a time of fun. After all, you get presents, candy, and time off school. Holiday hijinks are a part of growing up.
Adults, though, need to learn how to change their view of the holidays. The things that were funny when you're a kid are no longer in force. Plus no one thinks it's fun to buy you presents anymore.
You can still enjoy the holiday season as an adult, but you do need to adjust your expectations.
