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.
... I'll let you in on a secret. Big people are exactly the same as little people. They're selfish, squabbling children whose motivations are jealousy and greed. No one becomes big when the hit adulthood. They just become better at hiding how small they are.
