Blessings

Jacob came home from school very excited and he said, no home work for two days. I said why? He said,"Because, we have a field trip tomorrow." And I said, oh ok. He said,"Mom, it is a blessing! And He ran to the house and grab his book and started reading. Remember, it is raining, so he didn't ask to go out. Which is what they usually do.
Can you believe it? Should I be concerned? I guess, we all look a blessing in different way. I thought it was funny!
