Office ID

I was working out of a colleague's office who is of much higher rank than I am within my company. Normally when I call people I work with they answer briefly with something like, "Yeah?" or the even briefer, "Yuh?" But when I would phone them from my co-worker's desk and his name would pop up on their caller ID, it was as if I'd suddenly been promoted to a position of great importance. At least until I said "hi" and they realized it was me. The relief in their voices was a delight.
