"I've been resting, but if you want I can show you a hill about 10 minutes from here that we could rest. We can meet up there in one hour....if you two want to stick together that's fine but I'll be alright on my own, I need to find my luggage before someone else does....it's important..." I say this in a totally relaxed but slightly stand-offish tone conveying my resolve to do as I please.
Hey if you guys are wanting to continue this later or tomorrow or something that's fine we can just say to be continued and then start out next time by meeting up at this place.
