One time I had a 16 year old.... I did a little test, and I picked her up then put her down 10 times to see the actions. She was "driving like daddy" twice, "making sandcastles 3 times, "cooking like mommy" once, and "hugging the bear" three times! The last one was "browsing web", which any age can do. And she didn't walk like an adult/teenager, she ran like a kid!
