Cerberus, Martin?
Moi? Ouch.
Straight from the Horse's mouth is brilliant, both title and content.
Frank and Ann,
It's probably a good idea to tell them which poem is being alluded to, don't you think? Frank's is indeed a good 'un but the well-known poem i.e. Auden's letter, eluded me to begin with, and I'm not sure which John's refer to either. Duh! It's
To a Mouse. (I must get more sleep - it's affecting my brain

) Isn't that just a parody, though, as well?
And how do you define 'well-known'? Mine's based on 'Abou Ben Adhem' and I've met people who've never heard of it, though
I'd call it well-known.
I just wish they'd defined the comp a bit better, that's all. The 'character' bit is somewhat open to interpretation, as you say.
