Difference in Kids

Wow its amazing to see how different 2 children can be. Faith is pretty laid back. Jason is, on the other hand, never stopping. Why is that kids try to mess with you more when you are outside with friends? Jason will not listen at all when he is outside. I've have tried everything. I have even put him on time out when we are outside. Now to do that, I literally have to catch him (which you know is hard) and make him sit down next to me. Then you have to stop him from getting up the entire time he is down. LOL 3 minutes never felt longer in my life.
