I Fell in Love with Spring

2020-05-12

I fell in love with spring
With budding trees, and warmth and flowers
The grass that grows and birds that sing;
And its occasional blustery showers.

I fell in love with summer
With still, warm nights and longer days
Mixed with rains, and distant thunder -
And resting daily in the sun's bright rays.

I fell in love with fall
Its cooler air and plentiful harvest
How the leaves in bright glory us enthral!
They're painted by nature's own great artist.

I fell in love with winter
And starlit skies and frosty nights

Spring in Maine

2020-03-30

Spring, when are you coming
With your warmth and sunny days?
I see tiny buds outside
Ready to burst forth
Waiting for warm, sunny rays.
But snow lies still on grass and lawn
Slowly melting in the rain.
A cold wind blows today -
It is spring in Maine.

Before long, summer will be here
To rocky coast and beach's delight
When gift shops line the road
And no one heed the lobsters' plight.
Summer! Sweet desire of our state
As for now we long in vain;
Here in tiny snow-flakes falling
It is spring in...

Short Story: I'm So Sorry

2019-09-06

If you're reading this, let me just say that I'm sorry: So very, very sorry.

I didn't mean for any of this to happen. I'm beyond devastated for all of the lives lost - and the countless destruction it brought. I have no words to express my regret and shame for what I did. I can only hope that whatever is left of humanity will go on, and one day build a new and better world without the mistakes we did.

Yeah…...
