Thank you guest for the first request. Hope you like it. Also, Acciopotterevans, your story is in progress.
"Today Tooney and I had a burping contest. I won, obviously."
Lily looked at her old diary, which had butterflies on it, and a little pink lock, remembering that day. She had not, in fact, won.
"Buuuurrp" Petunia let out a large burp, finishing her soda.
"Buuuuuuuurrrrrppp" Lily belched, a few minutes later, trying to one-up her sister.
"God Lily. You make everything a competition." Petunia groaned
"You're just mad you can't make as magnificent of a burp as I can." Lily stuck out her tongue.
"I could too!" Her sister protested.
"Could not."
"Could too"
"Not"
"Too"
"Not"
"Too"
"Prove it then." Lily said, crossing her arms.
"We haven't any more soda" Petunia said.
"Mom and dad have more in the fridge." Lily said
"They said we couldn't have any of that! We'll get in trouble"
"They won't notice."
"Alright."
After Petunia came back with two bottles of orange soda, the girls started chugging. After Lily had drank about half her bottle, she let out a magnificent burp. But Petunia was still drinking. Several minutes later, Petunia burped.
And burped.
And burped.
"Aha! I win." She said triumphantly.
"No fair. You cheated." Lily said.
"Did not"
"Did too"
"Not"
"Too"
"Not times infinity."
"You can't do that!"
"Can too"
"Not"
"Too"
Lily smiled, looking back. Not all stories had a happy ending, but at least she had happy memories. She made a mental note to show her diary to Harry, when he was older.
