same kind of question again

0Hi,02br
02br
00Sorry to ask a question on the article again but wish I can get an answer to this if it is a valid question.02br
02br
00On a thread titled "Uncountable noun that is preceded by the "a"", started by victorycountry, Mr. M said in one of responses that "In Most cases, Paco-01del00as in many other structural /lexical choices we have looked at here02del00 it is the speaker's concept at the moment."02br
02br
00Then, I think he went to elaborate his points with these two examples.02br
02br
00poor attendance and a poor attendance02br
02br
00For 'poor attendance', I think he said that the speaker is seeing uncountable qualities.02br
02br
00For 'a poor attendance', I think he said that the speaker is seeing countable images.02br
02br
00How about these? Can you choose a pair and tell me what the speaker is seeing (conceptualizing??) in your words?02br
