Window fishing
(Book)

"Rudeday dreams of creating art that brings people joy but instead, he paints to pay the bills. His days and nights are long, until one day he hears a Tap! Tap! Tap! at his window. What could it be? Rudeday sees a piece of string with a paper clip tied to the end of it, coming from the apartment upstairs. Rudeday has a brilliant idea. Rudeday carefully paints a fish and attaches it to the paper clip, starting a window-fishing exchange with a little boy upstairs. The pair swap paper fishes back and forth every day. Rudeday is finally painting for fun but he wonders if he will ever meet his window-fishing friend."--,Amazon.com.
