Besides IJ, I don't think I have any real obsessions as such, but I like dabbling in writing a bit of poetry. Here's one:
Said This
Whoosh sighed the wind
Whish replied the trees
Hush whispered the earth
Buzz droned the bees.
Yip-aye sang the coyote
Growl said the bear
Hush whispered the earth
Thump thump went the hare.
Crackle said the lightning
Boom said the thunder
Hush whispered the earth
Sleep murmured the rotunda.
What's this? asked the man
It's ours, said the other
Hush whispered the earth
Then he killed his brother.
