man's best friend?

It's official, Sammie doesn't really like us anymore.

He loves our next door neighbor Sera and has pretty much assumed her as his new master. He spends all of his time on her porch, picks his head up when he hears her voice outside the family room window, runs to the backdoor when he can hear her outside with her dogs and bolts out the door each morning to sit on her porch and wait for her to return from her 7am shift at the hospital. Last night around 10pm Patrick went outside and called for Sammie to come in since we were getting ready for bed. He called him for a few minutes and when he never came Patrick walked outside with a flashlight to look around for him. Yea, he was sitting on Sera's back porch just staring at Patrick and it took Patrick calling and calling for him and then eventually dragging him home for him to return to his OWN home.
I just came home from class today and was in the house for about 10 minutes before I came back to the computer desk and when I walked in the family room Sammie is lying there on his bed. Never got up to greet me. Never picked his head up when I walked in the room.
It makes me kinda sad.
