Army up my sleevey

When I cough, Mommy used to tell me to cough into my hand. Then my teacher told her not to. Instead, Mommy now tells me to cough into my sleeve. Usually, I put my elbow up to my mouth and cough into my sleeve. Today, just to be funny, when Mommy told me to cough into my sleeve, I poked my mouth down inside my sleeve... like my arm! Mommy and Daddy nearly had an accident (in the car as we were driving) they laughed so hard! I like making them laugh!
