I ran into these two (who I believe were down visiting from Washington) up in the Hyde Street Pier area. Cooper (the bigger of the two) was really, really interested in going swimming, which I guess was a little out of character for him. But both of them were really, really interested in saying hello to me, which is not out of character for them at all, but which is pretty unusual for the breed.
Just goes to show: you get ’em young and you socialize them well, and you can do a lot to make a happy, social pup.
