At the Ojai farmer’s market there was a guy standing under a hand-written sign that said “free hugs”. Unkempt, immobile, unsmiling, making eye contact with no one. Perhaps not surprisingly, apparently invisible to passersby. Curiously he seemed bemused when I took him up on it; but after a pause gave a good sincere hug, firm but not invasive, perfectly synchronized release. He smelled faintly weird, but the end result was transformative: I felt noticeably good the rest of the day. How cool is that!
