One to Speak, One to Talk

A course is of course
hoarse with its own 
whisper. A way is one
way to sway. To sway
is to render. A sentence
cut short demands a
lengthier exhortation
in the next. To be on
the side is to be on one
side of the wide river 
between. A tender 
sender bends to avoid
the appearance of bleak.
