Who Am I To Blow Against The Wind?

from Paul Simon's "I Know What I Know", on the Graceland album.  I guess Jim Croce put it a bit more graphically 14 years earlier:  "You Don't Spit Into The Wind".  Not to mention The dB'song titled "Spittin' Into The Wind"....

Did I have a point?  I don't remember.

Who am I To blow against the wind?

I know what I know - I'll sing what I said

We come and we go

That’s a thing that I keep - In the back of my head

I know this picture has been posted several times.  In a couple of versions.  But it captures the "wind" thing.
