Here's a frivolous post as it's Friday and a holiday weekend for some of us.
In the manner of those questions designed to establish personality type, such as "would you feel driven to straighten a picture that was hanging squint?", what do you feel about a gap on the bookshelves such as is pictured here? Would you be rushing to fill it and have all your books soldier-straight and supporting one another with the shelf nicely full, or does that space with books leaning in a relaxed manner either side appeal more and speak of room to expand your collection, i.e the future occupants of those few inches are perhaps yet to arrive?
I ought to say that being short of shelf space here once again, that bit is only empty because we overfilled it before and all came crashing down, but I rather like the sense of possibility and the absence of cramming.
So, instinctively, do you mind the gap and want everything lined up together (without being squashed or double-stacked), or does a little breathing space appeal more - what's your inclination?
