Old photo booths and the marvel of Instagram present convincing evidence of a goofy smile. Nonetheless, I smile regularly and laugh all the while.
Often the best discoveries are something of a surprise. Love the fresh thrill of the new, far off places, unusual dreams, good design, and a great melody.
As for that hypothetical other hand. Spirited, caring, and creative in nature. However, truth be told it could just as likely be the very things I've missed to image. A lovely and lively work in progress. A killer smile, all the better.
