I make many text files, usually called scratchpad with a some meaningful to me prefix, though always on a computer (with whatever text editor i find first), other wise random scraps of paper (usually 2nd hand office paper) or in a moleskine (yes i have multiple moleskines)

ah that may be the only reasonable explanation for this behaviour, I certainly will not be posting anywhere where my real name will be visible.
