I brought my friend on an overnighter, around 15km, low inclination, basically flat, he had around 25lbs on him, he had me stop short of the orignal finish line bc he's bitch made and couldn't walk anymore, so I told him the next morning we could walk that last part, around 2km, without rucks, just to get to the end, and then come back to our packs and return, he refused, so I told him he could wait for me to do that at our tent, then we would link up and return together, he refused even that bc he got offended I wanted to go alone and decided to start going back alone up to a refuge and wait for me there, and still held a grudge bc I wanted to do these last 2km.
