The Rainbow bridge
There's a place called Rainbow Bridge. It connects earth and sky. If a beloved animal leaves us, it goes to this very special place. There are green meadows and hills for all our beloved friends. There, they run and play together. There is plenty to eat and drink. The sun is shining and it is pleasantly warm.
All the sick, maimed, injured or old animals are young again, healthy and strong, just as we remember them in our dreams of days gone by. They are happy and satisfied, except for one small thing: each one of them is missing that special someone who is not with him.
They are all running and playing together. But there comes a day when one suddenly stops and looks into the distance. His body trembles. It leaves the group. It starts to run. His legs carry it faster and faster.
Your friend has discovered you, and when you finally meet again, you are happily united, never to be parted again. Happy kisses cover your face, your hands caress the beloved head of your animal. You see again and again into the trusting eyes of your friend who was so long absent from your life but never from your heart.
Together you are crossing the bridge ...
