It's great that you do not think so, but, the conversation needs to happen anyway so everyone has the Same expectation.

One of our searches was for a camper (not a backpacker) who walked out of the campsite, got turned around and ended up some miles from camp. My protocol even for day hikes is to always tell someone you are leaving the group no matter what.
