Haha we have all been through the Teenage Timmy phase before. It makes me reminisce about that time in my life when I also started to distance myself from my parents a bit.
I love how you are looking for new ways to interact with him though. Also being conscious of the fact that there is a middle ground between overbearing parent and aloof caretaker is key!
I will try to remember this post years down the road when my daughter goes through the very same phase. Hopefully I will be able to manage it as well as you seem to be. Thanks for sharing!
