Today I learned how to have a highly expressive engagement with people who don't speak your language nor do you speak theirs.
Step 1: Go out in the asparagus field with them and start collecting previously pulled weeds.
Step 2: Work for a few hours with minimal words while you work up a sweat.
Step 3: Start singing a song to yourself.
Step 4: Get a whole lot louder, signing along with anyone around, melodically yell out someone's name or made up words in a high tone while the others take medium and low tones.
Extra Credit: If you get someone to join your work party who wasn't even going to work that day because you were so loud and jovial, great job!
