What a stupid title.
Why does the author blame the $10 lifeboat? Sounds like because it is only $10, so it should be blamed for such a mess the author and her husband made.
The author is cheap and stupid.
The parents tried to blame the rubber boat other than themselves. When I go to the beach with my kids, even they know how to swim, I never let them out of my reach.
This statement is wrong. Please refer to "Help prepare your 10-14 year old to stay home alone safely" http://www.toronto.ca/health/injuryprevention/youth/athomealone/index.htm
