If you don't know his blanket is hid in the bushes, how do you know the kids have pissed on it? Edited to clarify the lack of clarity in the above question when couplet six starts with, "Now that his bedding is so soiled I wonder where he’ll sleep tonight." which gave rise to my confusion about how "N" knew the blanket had been soiled. "In line five "N" does not know who's blanket it is, but in line 11 he does.Is his the filthy blanket hid amongst the bushes in the park ?,
those kids have used it for a toilet, soaked it in their nasty larks.
The imposition in the first part of this quote is felt by "N," the second part (for me) needs more wording to make sense, and also that the focus of the last 4 words is not a follow on from "N" feeling some imposition, it is something that "N" supposes the big issue seller feels, ( from I presume, a life of debauchery). ( Why do I think I know what you are trying to express but others may not? Because I read quite a lot of poetry and come across lack of clarity where the sequence of thought has to be filled in).imposed upon by his misfortune, self indulgence now regret.
I just had another thought about those last 4 words, that "N" is familiar to the big issue seller as intimated in lines1, 2 and 3 and that maybe the "self indulgence" was the narrator buying an issue or two in the past that he now regrets because it has set him up for further imposition in the future (obviously this is just a guess). As I say clarity needs to be brought to bare here,
If the whole thing is a scenario played out nationwide, then I ask myself if you have given me a new angle on the scene or cliché after cliché, and it's the clichéd feel I get from this not a fresh angle.
For me the work is more than a little insensitive to the plight of the homeless whose situation is hardly a subject for mockery or patronising reference. I can't help feeling that in part the poem, however tongue in cheek, expresses prejudice and a lack of empathy.
