To say I keenly felt the loss of my previous coffee is like talking about the minor seismic event at Pompeii or the spot of financial bother occasioned by Lehman Brothers.
My writing ritual is pretty strict in that coffee needs to be by my side at all times. Is there as momentary distraction, hydration (no, coffee does NOT dehydrate, MYTH!) and olfactory focus.
I won’t say my ritual is anywhere near as strict as the ritualised boozing of Dylan Thomas or Victor Hugo’s habit of writing naked, but if you have to find some way to nail yourself next to your writing implements, a cup of espresso is my anchor.
