She needs a messenger

She was very nervous. After much thinking, she'd take the decision to pass the letter to Sid. 
The best way was through books, she decided when she couldn't think of any other way.
She was too shy to tell him face to face. She was afraid she might blunder.

She collected the class notes that she used to borrow from Sid, which gave her reasons to talk to him.
She slipped the letter in one of the notebooks. 

"Hi, Where are you going, Reena ?" called Neha, the chatterbox, from behind. 
"To Sid, to return his notes", she told her, fearing of the nervousness in her voice.
"Ohh Great! Do you have his Economics notes ? Hmm...Let me see.." as she picked up couple of notebooks.

Reena's eyes widened. Neha was infamous for her gossiping which led her nickname BBC. 
I am caught, the news is going to spread like forest fire, she foresighted. The trajectory of the news from Neha to friends and then to Sid painted before her eyes. 
How stupid she looked in the painting watching Sid looking her. She couldn't decide what his face expressed? Was he angry or Was he happy ?

Neha shook her. "Hey Alice in wonderland. I am taking this note. Tell Sid I'll return later" she said waving the book as she left.

Reena murmured curses at Neha. "Now what to do. I am dead now ?" She kept the books down at the steps. And started searching the letter. Fortunately she found it.
She sighed, loud enough to attract those around. She smiled at them, turned around back towards home, deciding that she would return the books next day, with a fresh new start....
