You've just

You gotta have faith in someone
for the good you've known
but you tend to watch out 
for the bad you've known, too.
Preferably from them, and not 
someone else. And without judging
either of those damn two. Second 
person or third - don't get that shit
crossed! The one in front of you
didn't pull that off, keep the fold
on your squint, you can peep okay.
And your mouth? Well, better a gag
than too shoes, trying to soft-shoe 
or moonwalk back out of these
misconstrues. You've just got
to be wiser in your serpentine
coos
