As if the book in front of your face isn't enough of a hint. Some people need it spelled out.

A wonderful sock for people who love books, but hate being disturbed whilst reading! Blue Marle Women's Crew socks with 'fuck off I'm reading' on the side of the sock. 

Blue Q socks are made from woven luxurious combed cotton for softness, nylon for strength and a touch of spandex for long lasting fun! They are a lightweight fashion sock, but still excellent quality with unique designs and great graphics.
