As a teenagar, Klaus found himself doing jobs around the house at home. Being related to Santa Claus isn't as fun as it sounds, and when he's your dad you know that you have extra chores to do. Wrapping up presents around Christmas time was the biggest concern for Klaus before he moved to America, and it meant that he had to work incredibly hard. It never felt like a chore to him though, rather something he wanted to do to make a lasting impact on the lives of millions of children around the word. That's not to say it was all fun and games. It definitely taught him the value of hard work and the way that your actions can leaving lasting impressions on the lives of those you touch. It set him in the mindset to always be a happy go lucky person and to make sure he always gave the best vibes when he was around people. There is a lot that can be taken from his childhood.
