Some decades ago when I was still an engineering student, my team had to present an electronic assignment. The damn circuit didn’t work, no matter what I did. So I decided to go ask the teacher for advice. I walked away a couple of meters, when my teammates told me that the circuit finally started working. As soon as I went back, it failed again. We soon determined that it failed only when I was near it. My teammates presented the assignment while I was at the other side of the lab. We passed the assignment, and sure enough, when I approached again to pick up my things, the damn circuit stopped working again.
