Nell, Abby, and Emily went into San Francisco today, and Amy, Sally and I lazed around the house until the afternoon, then went down to the beach, Sally with her surfboard and wetsuit. The surfboard attacked her leg early on, so she spread out in the sun to read, exposing her already red shoulders. She is in a half-not-serious teenage grumpy stage, which shows itself particularly when her mother prognosticates about the effects of lying in the sun. Amy and I took turns to frolic in the surf, which was lovely, cold but not too much, although the waves were hard to catch. The tide is high in the afternoons.
