Re: Waste of time
well... (joke icon aside)
I would say the time spent by language teachers to force upon you their version of a poem's interpretation is a waste of time.
Question for the teacher: did you write it? No? Then Why do you think you know what the poet meant?
(yes, I have a bit of a trauma there - no, I don't want counseling, reading some Benn or Gernhardt[1] and having a few drinks is therapy enough)
