It wasn't exactly that crepes were something that Aziraphale was obsessed with as much as he'd had his heart set on them and had been denied so they were rather a large part of his focus at the moment. But it would pass in time, he'd move on to the next great thought of the moment, but there was certainly a fixation at the moment.
"Were he to be well rounded a few books might not go amiss, and some champagne might be a welcome addition." He suggested, certainly man did not need much to survive but would it be a life worth living without some of the finer things? He thought not.
"The world I know? Well it is the world." He said simply, "Created some time ago, inhabited by humans, all very normal you see." As it was all meant to be, according to what he knew of the ineffable plan, as much as anyone could know anything about the ineffable plan after all. Maybe this was a part of it? Who was Aziraphale to say otherwise?
