Ladder

Across the road in the rain was a ladder on a roof; the ladder not rising up from the ground below, but sustained, as it were, on the roof. Why a ladder on the roof? The rain had obviously nothing to do with it- the ladder had been there for more than a while. Though perhaps there was a leak in the roof, in which case the rain had everything to do with it. Though not this rain in particular, but rain in general.
Can one isolate rain in particular from rain in general? There is, you might argue, no rain in general, only rain in particular. 'Rain in general' merely an idea, words floating in someone's head, while rain in particular is rain, though a pedant might object that even 'rain in particular' is a mere sequence of words. Yes, but we all know what is meant by 'rain in particular'; we can point at it, while it is there. But 'rain in general'- what the hell is that?
