Query: lol - laughing out loud

I found myself laughing out loud while reading in the carpool or at night while my spouse was trying to sleep. I would recall something from the book and chuckle about it later, making people ask what was so funny, I would explain and the laughter would continue. Laughter really is pretty good medicine - a great read for those needing the old frown turned upside down.
