Written for my wonderful girlfriend, Lanna - I hope you like it :)
It was 2 o'clock in the morning in Hogwarts library, and Hermione was tip-toeing around in order to find a specific spell book. She was under the impression that considering the time, there would be no one else present, however unfortunately, she was wrong.
"GRANGER, what are you doing out of bed at this time of night?!"
Nervously, she replied "I performed an awakening charm on myself so I could do some extra homework but I don't know how to reverse it and now I am finding it hard to sleep so I thought I could find a book to help, sir."
"Regardless of whether you can or cannot sleep, this is unacceptable." Snape retorted.
Out of the corner of her eye, Hermione saw Snape grab something off of the table and hide it behind his back.
In a curious voice, Hermione enquired "Sir... what is it you're hiding?"
"Nothing that concerns you..." Snape darted his eyes quickly around the library to see if there was anyone else present "...unless..."
"Unless?"
Snape leaned closer to Hermione. "...I've been trying to function this muggle contraption because I believe that it will be incredibly useful to me, however I am finding it somewhat... difficult."
"And you think I may be able to help you?"
"Precisely."
"What is the contraption in question? A drill? A television?"
"...hairspray." Snape said in an embarrassed voice.
"Hairspray?"
Snape seemed somewhat angry now "Yes, hairspray! To stiffen locks of hair! That is the muggle contraption! Well, can you help me or not?"
Hermione muttered under her breath "Professor Snape in the library with a can of hairspray, almost sounds like a game of Cluedo gone wrong..."
"What was that, Granger?
"Nothing sir... I may be able to help."
"Okay, how does it function?"
Hermione sighed and took the cap off of the can and pressed down on the button which sprayed some liquid into the air "Like that, you spray it on hair, wait for it, and then it will harden."
"Ah, I see. Thank you, Granger." Snape suddenly squinted his eyes at Hermione, his usual cold self back to normal "If you breathe a word of this to ANYONE, then you will have 50 points taken from Gryffindor, understood?"
Hermione smirked "Yes sir!"
Snape hid the hairspray under his cloak as he walked to the exit, looked around the corridor, and then ran as fast as he could.
As soon as he was out of sight Hermione burst into laughter - "Snape using hairspray..." She thought. "What next? Hair curlers?! God I hope not..."
