I was at shul on Sunday, not during a service, but during a meeting. A parent and child were sitting in front of me. The small child's legs were far too short to reach the floor, and her feet were kicking the siddurim in the rack on the back of the seat in front of her, repeatedly. I could not see her face, but she seemed to be doing it on purpose and enjoying it. Her parent was sitting right there, and cannot possibly have missed seeing this, but did nothing as it continued for several minutes. I don't think anyone else could see what was happening. It was bothering me immensely, but I could not decide whether to speak up and potentially embarrass the parent, or stay silent and allow this disrespect to continue. In the end, I kept my mouth closed. Several days later, I still cannot decide whether I did the right thing.
Would it be proper to correct a child such a situation?
