Cover your mouth and shout

Meredith and I had a game of Monopoly this afternoon while Daddy and Reegan were having their nap. Somehow luck was on my side and I was getting all the money from Mr Rich. Feeling excited, I let out a 'Yay!'.

Meredith, being the sore loser she sometimes is, was not at all happy. She said that saying 'Yay!' was very rude. I tried to explain to her that no, people say 'Yay!' when they are happy. She said that I could just shout if I was happy. But I couldn't, the men were sleeping...

"Cover your mouth and shout."

Now how pathetic would that be???!!!!
