Onward, ahead or so

 This is getting to first base with a poem.

to start i put nuts in a basket. Gathered are feelings and i called them nuts.

he reached into my mouth and unscrewed a post he put in to hold a crown.

i said that right. the post is loose, he(my friend the dentist)'s going to put in a larger post.

 (here my wife would say "he's not your friend, he's you dentist." and i'd say "he is too my friend.")

  now, on the next day.

I'm going back to (my friend) the dentist;

I'd rather avoid the thought, however, I respect the man. 

I'd look ahead happily If i had half a wit.

 i'm going to let him twist a larger screw into my jaw.
