The FAO building is vast and I keep getting lost. I have, however, found the quickest route from my office (on the 7th floor of C wing) to the cafeteria (on the 8th floor), which has great but cheap food and a good view of the city.
Getting lost in the building doesn't worry me to much because all the corridors are lined with heartening pictures of grains and fields and poor people eating. A less heartening thing about the corridor is all the intimidatingly closed doors, behind which there may or may not be friendly people sat in air conditioned rooms.
So my kunundrum is whether to leave my door open and welcome would-be callers to build my personal network, or whether to close my door and save the energy of my air conditioner.
