Thats the thanks you get! All the time spent with them, caring for, cleaning of, nurturing, etc. They get old and then they leave home!
That reminds me of some vehicles I have owned over the year. Not so much for the vehicle, but for the good times we had traveling in them. Used to own some really large station wagons that held so much more than anything made today. I used to love to travel. seems I have lost all interest in traveling now.
