The phrase "are the fence" can refer to being indecisive or uncertain about a situation. Synonyms for this expression include sitting on the fence, straddling the fence, and being ambivalent. These expressions imply a lack of commitment or clear stance on a particular issue. Other synonyms could include being neutral, hesitant, or undecided. It is important to note that while it may be necessary to be cautious or take time to make a decision, constantly being on the fence can result in missed opportunities and a lack of progress. Therefore, it is important to weigh options carefully, but also to make a decision and take action when necessary.
