I was working in a giant field that had been freshly tilled and Barack was showing me how to pick out the rocks from the soil and toss them to the outskirts. As I pitched my first few rocks he was very encouraging, and placed his hand on my shoulder at one point to offer me kudos for my efforts. There was a crowd of dusty onlookers that were watching him instruct me. I remember feeling excited about what we might plant there.
