Both conventions have been smattered with "lay" people, their heartfelt stories, all seeming to have resolutions with political ties. Kind of like quantum physics, the more I hear, the more questions I have ... about both parties and their speakers. My "cup runneth over" with voter's apathy. I thought by watching both conventions I would come out with a clearer understanding and maybe even a "choice". I'm still not there; I'm still sitting on the fence. I tend to be an "out of the box" thinker, but I'm getting to where I want earplugs. Even if I burid my head in the sand, I'd have to choose which side of the fence! haha ... one more speech, whew!!!
"bury your head in the sand" - to refuse to think about an unpleasant situation, hoping that it will improve so that you will not have to deal with it
The imagery comes from the (erroneous) belief that ostriches bury their heads in the sand. The idea is that, with one's head under the ground not able to see or hear outside, they aren't aware of what's going on: usually at a time when they SHOULD be aware.
