The idiom “sitting on the fence” is an oddly appropriate one.
On a surface level, it makes sense. There are two sides to a debate and a fence dividing them. You can’t decide, so you’re on the fence. Here’s the other thing about sitting on a fence:
It’s uncomfortable.
Everyone wants you to take a side. Sometimes, you just can’t. You see both sides too clearly. So you just sit there with a fence post up your you-know-what, staring longingly at two equally comfortable-looking coaches on either side. How can you choose?
