Walk in the park turns out to become tragedy

A couple, their dog and three childern went for a walk in the park when the dog fell into a canal.The couple,having a close affection with the dog,jumped in and drowned!The children were left as orphans and the dog died too.
What people do for their pets is truly shocking.Maybe in this case,the couples did not anticipate the dangers posed by the canal and the possible endangerment of their lives.However,this goes to show that pet owners usually grow attached to their pets.The couple did not hesitate to save the dog and their childern became orphans due to this mistake.The couple are "blinded" by their love for the dog and therefor lose sense.Is this what they call the power of love?Are pet owners all like that?Another example is well-known Oprah Winfrey crying over her dying dog.Are pets really so important to their owners?
