We have a shed in our back yard where we park our bikes. There's always been a lingering smell of crap despite the fact that the floor of the shed is clean.
Turns out, it's not the floor where I should have been looking. Someone's been flinging dog crap up there. Given that this bounds on two of our neighbour's properties, I'm looking outside the current set of residents in our building, who have no dogs regardless.
Immature poets imitate mature poets steal bad poets deface what they take and good poets make it into something better or at least something different. The good poet welds his theft into a whole of feeling which is unique utterly different than that from which it is torn the bad poet throws it into something which has no cohesion. A good poet will usually borrow from authors remote in time or alien in language or diverse in interest.
—T.S. Eliot
