One might think that beds are made for sleeping in, but they’d be wrong. Apparently, unbeknownst to men everywhere, beds are in fact made to hold as many pillows as possible. Only a fraction of the pillows present are actually functional at any given point in time, while the rest are there for some unstated purpose. Sleeping on the bed requires several minutes of relocating pillows to suitable locations, which of course will be designated by the woman who placed them to begin with.
I can imagine need for second pillow for those who like to cuddle with pillow when sleeping or need an extra prop support when sitting. My creativity runs out when envisaging need for third pillow or more.
