Certainly children have cried while I was on a plane but the worst I have ever heard has come from adults.
I sat in front of 2 men and for 3 hours they bragged to each other about their houses, cars, art work, weekend houses, expensive trips and their rich and important friends. I thought I was going to scream, they never shut up. Then the gossip session started all in loud voices......... until I heard them mention someone I knew...... and then their voices turned to whispers. Dang it! :)
And it’s only going to get worse now that they’ll allow people to chatter on their cell phones all through the flight.
