I find the prolonged and integrated sounds of rain and pen so audible, so apt. Yet there is contrast, too, between the steadiness of rain and the frustration suggested by repeated pen-clicking. Such possibilities of interpretation! Thank you.
The haiku wonderfully generates a pent up feeling for me – impatience, anxiety, maybe obsessiveness. I admire the haiku craft in the repetitive use of the words rain/again to stimulate our experience and like Jan said the contrast between rain (nature) and human nature works well.
Ah, yes, so many of us click our pens for various reasons, and sometimes third parties become involved…
all my mistakes
each click of the pen
the robin moves

The (European) robin is very much a Christmas seasonal reference in Britain and Ireland and a Winter reference in general, not just poetic, as it's mostly the robin that sings through Winter while others become silent.
