"There's an elderly woman fussing with the top of the cream pitcher, trying to get it open. Her purse sits on the counter, but as I approach, she picks up the handbag and anchors it to her side, crossing her arm over the strap. "Oh, that pitcher can be tricky," I say. "Can I help?" She thanks me and smiles when I hand her back the cream. I'm sure she doesn't even realize she moved her purse when I got closer. But I did."
