Twilight's OCD

The knock on the door seemed endless.

"SPIKE! Open the door!" Twilight always had to yell for Spike, being the super lazy dragon he was.  Spike ran down the steps as fast as his little legs could carry him.

"Hello, darl- Spikey-Wikey!" Expecting Twilight's greeting, Rarity's bright red blush faded.  Her crush did not answer the door.  Instead, a pimple-faced dragon opened the door and blushed.  Rarity rolled her eyes.  "Spikey? Can you get Twilight for me?" Spike angrily stomped off.  He HAD to get Twilight! Twilight stared at Spike.  He motioned to her that he needed her to LEAVE her bedroom.

"Rarity!? H-Hi..." Twilight's lavender coat had become red in the face.

"H- Twi- um..." Rarity struggled to tell Twilight her secret.  But, it came out all at once.  "TWILIGHTILOVEYOUPLEASEGOOUTWITHME!" Twilight, who understood EVERYTHING, smiled her 'I love you' smile that she usually showed her books.  Rarity blushed back and kissed the book-loving mare.  Twilight needed to tell Rarity.

"Rar-ity...... I have OCD.  I can't go out with you.  It'll be too risky." Twilight stared at the dressmaker's hooves, than looked up.  Although, she tried to, had to, hide her tears.
