The in the office haiku

In my back a sound – 
if short, it’s the rolling of
a tire, if long: rain

– Leonard Blumfeld (© 2020)

Note
It turned out to be short. Since there was no engine noise, it must have been an electric car or a hybrid in electric mode. Can such dissimilar sources cause similar sounds? But both alternatives presented themselves to me without conscious reflection as I was sitting in my office with my back to the window, not bothering to turn around to verify.

The undulation haiku

An undulation
through the wall – sufi music
or vacuum cleaner

– Leonard Blumfeld (© 2015)

Note
Again the truth and nothing but the truth as it happened a while ago. Considering that this musical event did not last very long and did not develop, I now suspect that it was indeed the vacuum cleaner run at low speed to pick up a specific moderate mess and not the alaap of an Indian music piece.
