Watched my buddy get torn apart in his book club for hating a prize winning novel. He came back next month armed with reviewer quotes about the book's structure, totally changed the talk. Sometimes you need that outside voice to point out what you missed. He still didn't like the book much, but the whole group got way deeper into why it worked.

Been there! I photobombed a proposal at a castle once.

Ever tried using bright colored paper for your signs? I found that neon green stands out way more and people actually notice it.
