My dog Bama loves to annoy our puppy Gooby. The puppy can try to jump on the back of the truck or on the bed and Bama being up there already will stand in front of where the puppy is jumping, look down at him and push him down with his paw as the puppy jumps up. It's amusing.
Isn't that like life, we jump excited to make it up higher in life and something knocks us down before we reach the top.
Don't give up. Keep jumping, eventually like Gooby has learned you find a way to jump around the obstacle pushing you down and you succeed with a smile of joy at the victory you have won!
