"A dog can wag its tail but a dog needs more than that. Just like a person needs a purpose, a dog needs a purpose too. We don't feel good when we are just taking up space."
(from Jack McAfghan: Reflections on Life with my Master")
That is how my Dad feels right now. He is older now and he has been so used to being productive that it's hard for him to be so limited. I try to think of projects he can help me with.
You make a very important point.
A lot of what applies to us, applies to people too. We are, each one of us, loaded with vast potential. We were each brought into this world to serve a unique purpose. People should really think about this before they harm, abuse or abandon someone, two legged or four legged. Each of us has a gift and every one of us should be honored, respected and appreciated for what we have to offer.
If we don't or can't fulfill our purpose, we feel an emptiness inside that nothing else can ease. Please keep trying to create opportunities for success in your father's routine. Please tell him we love him, that always helps. We love you too.
