Titus' tail!

Now that you're a little speedster on your hands and knees, you are following Titus everywhere he goes.  

At times he picks up the bone he's chewing on and turns his back to you.  Other times he lays there and lets you harass him by petting his back, tugging on his collar, or grabbing his tail.  You literally crack up with laughter when he walks by you.  You sure love your brother!
