Frank Tassone’s haikai prompt this week is autumn comtemplation (shuushi). I will contemplate this idea more later, but these are my first musings. 

Brown leaf tumbles down
Crinkles, crunches underfoot
Ground has a blanket

Tree branches shivering cold
Amid changing, frigid wind

Update: Here is a haiku that is a little bit silly but also has a lot to do with autumn.

Coffee clichés come:
P.S.L. fever ignites
Cool temperatures
