Shout out to Internal_Ability's wonderful insight!
Your post about the coffee cup rim has stuck with me. A powerful idea which upon much reflection seems so on point.
That clever, yet seemingly gratuitous, bit of fun, Forrest placed within the context of the Borders stories. Two Borders, a Double Entry spiked for emphasis. Borders may be easily thought of as a Store(trove) that CONTAINS popular information, knowlege, fiction and adventures.
The line of sight beyond/behind the Rim was what truly amused and intrigued him. It made him Wonder... And He had to enter into two Borders (Toot, Toot lol) to look for the object of his search.
I'm sorry I was too slow in replying to what you shared. After you removed your post you instigated me to go on a mini quest to find you.
My old wheels are still sturdy but spin a bit slower these days, just aging gracefully, with a song in my heart.
Warm regards and thanks so much for your meaningful contribution.
