Every time I return home my dog, Lucy, goes berserk. First there's that sweet moment when she realizes that I have returned from wherever I've been. Then there is that mad dash to get to me. This can occur at a dizzying level of speed. This is followed by the jumping up on me, the piddling, the squeaking, and the frantic tail wagging. And the length of time that I'm away doesn't seem to factor in to her uber-excitement. I can be gone a week or 20 minutes. It's all the same to Lucy. And I love it for who else is so consistently overjoyed just by my walking into their range of sight?
Here's what I know about my dog. She is the spittin' image of the Father in the parable of The Prodigal Son. You know the story, boy is unhappy with his lot in life, asks dad for his inheritance, dad hands it over, boy blows it all and has to crawl back home. He is expecting to hear a litany of "I told you so's" but instead his dad acts just like my dog. Running, kissing, hugging, and I am undone by such a display of love - as I'm sure that son was. Like the Prodigal Son's Father, Lucy's mercy is neverending. I continue to learn a lot from her.
P.S. Oh yeah, and about that "put-out attitude" of the older brother. Definitely cat behavior.
