Recently, we watched Marley & Me. Anyone who has seen that movie and is the least bit sympathetic towards dogs probably cried just as much as I did during certain parts. It didn't make it any easier with Gordon actually in the room, watching the movie right along with us.
He was fascinated by the "bad-boy" dog in this movie, and couldn't seem to tear his eyes away. We even laughed (!!!) at the antics of Marley, which Gordon just couldn't wrap his head around. HE wasn't allowed to do ANY of the things we were laughing at Marley for doing! It's just not fair!
