LOL, well I say, kill the German (not really) who started saying that, EW... a poem can take any form the poet chooses, rhyming or not. EW, looks as if you and jabber posted at the same time... chatty grabbed your four words, so I'll try jabber's words:
storms, travel, over, rail

Storms---
what they bring to my kind
A big one brews outside,
while one brews in my mind
Tumbling over and over,
thoughts - pitiless and unkind -
travel through each higher nerve
leaving misery behind.
I rail hurt to the wind,
howls from both storms combined,
Baring soul to each storm,
full release I must find.

Ask that German if there's a saying about punctuation...lol.

And to get back to chatty's four words:

Eenie, Meenie, Miney, Moe
