Around the corner from the needle exchange we settled down for an extended period one afternoon in March. It was a half grey, half sunny day that was oddly chilly for Los Angeles. I had seen Christine on my way to meet someone else, and as often happens to me, I changed course and forgot completely about my previous intentions and focused all of my attention on this most ephemeral being named Christine. I am learning more and more that I must exercise great care and learn to read carefully the most minor outward indications that may serve as warning that I must tread very, very carefully.
