I was away with my son for the vacation when you commented. Thanks! I don't think we met before? Hi!
Sonnets are the most fun, thast's why I try to make them. Yeah, you can be a bit philosophical and folk sort of expect it!
What gets me, is how to organize the language. There are hundreds of sonnets in English from every year since before King Henry VIII, featuring the language of their times, so that some of the grammatical tricks which work best for sonnets are from hundreds of years ago. But modernistic ones are amazing sometimes.
I try to use all of the tradition, since it's a traditional verseform. Usually it's a kind of puzzle, like crosswords! Don't tell the poets I said that, though?
