If you have teens, you’ve most likely been on the receiving end of their “know-it-all-behavior”. I know I certainly have. 🙂 And I know I gave my mom and dad when I was a teen because I thought I knew it all too! If you’re the parent of a teen, you can pick up this humorous No Need For Google, I Have Teenagers T-Shirt for only $6.99. Shipping is just $1.99. This is a great deal for a tee!
