I got the idea for this activity from this picture
Have you ever played Mad Lib? It's a game where you write a story but leave blanks throughout and then have another person fill in the blanks to create a hilarious rendition. For example, you ask the other person for a noun, verb, adverb, common phrase, color, measurement, etc to fill in the corresponding blanks on the page. For FHE, Matt and I wrote portions of our "love story" and then had the other person randomly suggest words for the blanks. It turned out great! My favorite sentence from the night was "your lips reminded me of lips."
