How do YOU count pages?

[fragilephoenix]

Ok this is driving me a bit batty- do you all consider "a page" the front and back of a sheet of paper or is "a page" one side of the sheet? Whenever people post their page # update, I'm always curious as to which way they are counting.

(I always took "a page" to equal the front and back of a sheet of paper when it comes to letters.)
