I can't say that "dog" was my first word. I can however say that this dog is my first thought before I wake up and the last thought before I go to sleep*. This is Wilson. My best friend. My dog.
* After J read this he questioned why Wilson was my first and last thought of the day. I guess to make him feel better I will clarify that remark. Wilson snuggles up next to me before I fall asleep and then he wakes me up every morning to be let out.
