In Pakistan, valentines are exchanged in secret

Outside the gates of the women-only Kinnaird College in this central Pakistani city, boys shyly approach, bearing roses and small tokens of affection.

The girls, clad in a spectrum of reds, happily accept, even as they peer around nervously to see who is watching.

"Feb. 14 is a very special day for me to celebrate love because it was on this day last year that I met my boyfriend," said Sania Ehsan, 21, holding a basket full of chocolates and heart-shaped cookies to exchange with her Valentine.
