Spring at last. The snow is melting fast on the ground, and in the air the scent of possibility. I always get restless at this time of year, especially at night. I go on long walks in the dark, keeping company with wandering cats. They're always friendlier at night, less apt to scurry away at your approach. Most times they'll stick around for a pet and a scratch behind the ears; occasionally one will follow you for a while, and just when you've gotten used to its presence it disappears. Maybe that's why I have so much respect and admiration for cats. I'll take you for granted, they seem to say, but I'll never let you do the same to me.
