A brother (looked Moroccan/Tunisian) who came to the masjid with his son came for taraweeh. His son was standing beside me and he was standing beside his son. His son was constantly moving, coming in the way of my sajdah, leaning on me during qiyam and rukoo' to such an extent that I could've fallen and almost did a few times, and I bore it for 4 raka'ats. After the 4 raka'ats, I asked the brother to take his son to the sides as they were empty. He asked me why and I told him that he is disturbing my salah. The brother took offense and instead of moving his son or with his son, he just swapped places and the guy on the other side was being completely bothered during salah. I know it's not a good thing, but I was happy when they left after 8 raka'ats...
