I had a little chuckle after reading this

I lovingly call Ed a loud mouth Yank ... well he is a little loud, but he seems to yell in comparison to me as I am very quiet spoken. Which sometimes is misunderstood as being shy, but really my voice doesn't go that loud ... unless you are talking about screaming ... On our first cruise one of the CM's said "come on I need you to make some noise" After getting just a dull roar from the crowd, he said whoever makes the loudest noise gets a prize. I let out a blood curdling scream, and our tablemates jaws dropped to the ground, they just couldn't believe a noise that loud had come out of me

Needless to say I won the prize

It's just what they say; it's the quiet ones you have to watch out for.
Great advice
Oh, which excursion did they cancel?
