"Read me a Story"

My sister and I share a room. Two twin beds next to each other. She was asleep and I was writing a letter to a dear friend that's in the MTC (Missionary Training Center). I started hearing mumbling and then this conversation was born:

S: "Somebody read me a story"
M: "You want me to read you a story?"
S: "ahmm"
M: "Which one?"
S: "I oh a mmm"
M: "What? Which one?"
S: "I no no"
M: "Which one's your favorite?"
S: "uuhh I mmm"

Then She rolled over and the conversation ended just as fast as it began. I wonder if she'll remember this in the morning...
