<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">avoid making a decision</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sit on the fence that I've seen before include "Don't commit oneself" , "Remain undecided" , "don't choose either?" , "refuse to support either side" , "Refuse to commit oneself" .)
