This incident happened during my Sec 1 Scouts camp. That night, after dinner, we were supposed to go for a night walk at MacRitchie Reservoir. We were all kind of excited about it, this being our first camp and all, but we weren't really too thrilled about walking in a forest alone at night. Before we marched off to the reservoir, our leader gave us a bit of advice. He said that when we were walking in the forest and if we heard anyone calling our name, we should stay calm and walk straight ahead and not look behind us. This said, we all went off.
