An interesting camping experience from my teenager years

I was sent to a summer camp in Oklahoma. As I recall, it was pretty full. We had an established buddy system, if you have to separate from the group for whatever reason, you take someone with you.

We were preparing for dinner and fired up the vertical standing coal fired grills and I had to take a fat piss in the woods, so I grabbed one of my friends and said word for word "I'm gonna take a piss, come with" and pointed to the woods... 

We got to the edge of the woods, which genuinely was not that far from where everyone else was BUT it was down an incline making it seem a bit more isolated. My buddy leaned up against a tree while I went just a bit deeper in, but still within earshot of everybody, and I heard a voice call my name, which sounded exactly like one of the camp counselors. 

I shouted to my buddy and asked if he heard that, which he affirmed that he did. We shouted back to the counselers and other campers cooking and asked the same question, to which they answered yes. And saying no when asked if they said anything. 

I took my piss and left pretty quick, as the atmosphere was pretty oppressive and I did not want to stay longer than I had to.
