Have three hours at Logan airport, six hours of upcoming flight to Paris, look for a plug everywhere to work on my computer, spend an hour trying many, none have juice. I see a man sitting with his computer plugged, one socket free. Ah, finally. Are you plugged to electricity? I ask. Yes. Are you sure? Now he’s worried. He looks. Oh no! He’s very distressed, the battery he had planned to use in the plane is almost all used up. A man facing him on another table turns his face to laugh.
