On the journey to becoming a productive member of society I had to compartmentalize my inner child.
During my early schoolboy years, he waited patiently for the school day to finish so that he could finally resume his creative and playful pursuits.
As the education became more involved, he had to wait a little longer because of homework.
In university, the complicated assignments, group projects, and late night study sessions meant that he would often not get to let loose until the weekend.
The full-time job, commute, technical projects, work politics, and other adult responsibilities really did the biggest number on him though. Sometimes he would go without playing for weeks, or months at a time.
Today it's as if my adult mask has adhered permanently to my face and I can no longer access him at all.
One good part about having a kid is that you get to re-experience all of the fun kid stuff you remember, both as an adult and through the eyes of your kid. You can introduce your kid to your favorite shows/books/etc that you remember (and cringe at some of the stuff you forgot was in there).
