Thunk! Clunk clunk clunk.
I never realized how frequently acorns fall off trees in the fall until Lost Boy and I went on a date to a park in late September. I set our picnic blanket up under an oak tree so we could look up into its branches. We like to do this in the summer. But this time we eventually had to move because the acorns falling and hitting us became ridiculous.
Between that park date and living here at Grandpa's house with its exposed beam roof I've learned that acorns fall fast and furious in the fall, especially on windy days.
Whenever one hits our roof I'm momentarily distracted. Then I smile as it rolls down the roof.
