Lexile Level: 810-1000
Fall is finally here! Or, is it?
This may sound trite, but, fall brings cool nights. I cherish being ensconced and sibilated by the serene and mellifluous sounds of rain falling on the roof. The rhythmic pattering of the rain, followed by the pleasant, odiferous petrichor titillates the olfactory senses. It is an Elysian moment, to be precise.
Sadly, the experience is ephemeral, and we experience another warm day with 80 degrees.
Anyway, let’s stop the carping, enjoy the weather, and get to work!
The only immutable thing from Summer to Fall, is the arrival of the Pine Cone. You may wonder what is with the Pine Cone? But, take a moment to check this out!!
