a morning in creative writing class

tim sat wearily at the table, wishing he were in bed. he wished it even more as he listened to his annoying cousin's chatter.
"how was your two days off school?" elisabeth asked excitedly.
tim replied, "um...i caught up on my sleep."
elisabeth gasped. "how could you sleep the day away?! there are things to do! people to see!!!"
tim, annoyed, interrupted her. "Sleep, is the most, necessary, part of life."
elisabeth rolled her eyes. "that's why God created the moon, to tell us when to go to bed. the sun tells us to wake up!"
tim said matter-of-factly, "even God rested...yeah, God took a break, man."
elisabeth snorted. "so, like, let's sleep all day saturday and work the rest of the time. that's what you're saying, basically."
tim smiled prophetically. "okay, answer me this; what do we do in the seasons where the moon and sun are out at the same time?"
elisabeth gaped, astounded that something intelligent came out of tim (this early in the morning). 
"i guess...we...hibernate like a bear."
tim high fived elisabeth. 
"end of conversation."
"okay, oh by the way tim...uh...tim?"
tim had zonked out on the table.
"ZZZZZZZZZZzzzzzzzzzzzzzz............"
elisabeth shrugged. "how can he be tired?"
elisabeth yawned, putting her head on the table.
"i just don't...understand...him......ZZZzzzz........."
elisabeth has fallen asleep, as well...
