  Several weeks ago, we noticed a robin's nest in the tree in front of our house. Every day, the mother and father birds have watched the nest for approaching people and dogs to protect the nest. I guess it would not be so surprising to hear that the birds divebomb anything coming near the nest to protect their young. Several days ago, the eggs hatched and I've seen at least two babies. Since then, there has been lots of rain, wind and even a few hail storms, but the birds have persevered.
You have to respect a parent's ability and need to protect, so it was not so odd when my retriever approached one of the babies sitting on the ground for me to have ordered her away. The mother had been watching the baby, anyway, and despite her size compared to my retriever, I'm sure she would have taken after her had she not retreated. I watched at the window to see the mother hopping on the grass away from the baby. The baby cannot fly yet, so her moving away from the baby makes it follow her to gain it's strength and perhaps encourage it to fly. The beauty of nature is inspiring. Take away the cares of the world, the pressures, the stress, and all that is really left is family bonding, a parent to it's baby, the child to its parents and siblings and the nurturing and care that results.
I wonder, as humans, why we have made life so much more complex. The key to living, I believe, is to find the basic simplicity.. love and nurturing and make it the most important thing in your heart. Maybe that is what gives us the strength, despite all odds (like the mother bird) to persevere.
