Shadows

My dear departed wife collected dolls.
I am now collecting shadows.
Storage is not a problem.
This collection is not for sale.
I normally don't play favorites but this one has all my attention.
Its exact location is hard to pinpoint.
Google maps does not help.
It often appears under a passing cloud or nestled beside me in the warmth of my shadow.
Often it shows up in a dream, wearing a blond wig and a t-shirt that says I love Cairn Terriers.
I even wrote a long and beautiful love letter to it, but it was too long and too beautiful.
Now it's gone AWOL ... was it stolen or just a runaway?
Is there an app for this?
Searching FRANTICALLY!
I might put on a milk carton ... Have You Seen Me?
My friend Jenny collects sentences.
