Love-lorn college girls.

Library was just about to close for the day, and i was standing in the queue at the counter to get my books issued. Behind the counter was a young man and a young woman, young man was handling 'registration' and the young woman was handling 'return/issue'. I joined the long queue of return/issue . The 'registration' queue had just two chirpy college girls ( they were wearing the shalwar kameez uniform of a college i know). The man behind the registration counter called a few of us to his side to even out the burden of his colleague. College girls frowned. They didn't like it. The man after checking these girls' registration form asked for their phone numbers. Both the girls gave their mobile numbers. The two girls were nudging each other, finally the taller one asked 'sir, kya aapka naam jaan sakte hain?' Man: 'I am XXX, we'll give you a call to confirm your number, please write your land line numbers as well'. Girls were suddenly sad, while returning their forms, one of them said 'sir, please mobile pe hi kijiyega, aap karenge phone?'. Man ignored this question, but was smiling and then finally looked up at them and said ' THANK YOU'. Girls smiled. Both said in a chorous 'bye, sir' Man said a shy 'bye'.
