Question

What is the urinal puck in Miracle Life of Edgar Mint a symbol of?

Answer 1

From an interview with the author, Brady Udall:

"Q: What, if anything, does Edgar’s typewriter symbolize? What about his urinal puck?

A: Not to be difficult, but the typewriter and urinal puck don’t symbolize anything at all, not to me at least. I guess I don’t believe in literary symbols. To Edgar these objects are simply sources of comfort, replacements for the loved ones he doesn’t have."
