There’s an old saying in San Francisco - I know it’s in Texas, probably in San Francisco - that says ‘fool me once, shame on - shame on you. Fool me 17 times - you can’t get fooled again.’
Sometimes you think a thing is good, and then it isn’t. And then you find a reason to believe it will soon be good, but it still isn’t. And then you find a whole new reason to believe it will be good eventually, and, again, it isn’t. Sometimes this happens with players on the San Francisco Giants.
