A Colleague-cum-Friend (CF)
A colleague-cum-friend is a light in the dark when you are on a night-shift and have no one else to share your lunch, life and porn with. A CF is a constant guard, who swipes in your card and does extra work for you when you want to leave a little early. A CF is the only guide, who lets you vent out your frustrated tide, after a cumbersome day at the sea (office), with a smile.
Finding such a friend in the disguise of a colleague is never on paper, but indeed, the most desired perk.
