Sam and Tex are the best of friends...most of the time! Sam loves to throw the ball for Tex, but he gets quite upset when Tex picks the ball up and doesn't give it right back. So, I'm constantly saying "drop it!" to Tex and Sam gets the ball and carries it around, driving Tex crazy until Sam finally decides to throw it. Tex is really great with Sam; he thinks it is his responsibility to take care of Sam. As soon as he hears Sam in the monitor, he is up the stairs and laying in front of Sam's door. It is so fun to watch them together, and I only get nervous occasionally!
