Sounds to me like everyone was probably tired. Obviously I wasn't there but, trying to be objective, I can kind of see both sides. Except for expecting the person who is trying to fix their jeep to drop everything to become host extraordinaire.
Side one: My group just came off the trail and we are feeling pretty B.A. about ( pronounced: "A boat"... Get it?) ourselves. Therefore one might expect that bystanders might strike up a conversation about the recent adventure. Nothing happens, so automatically the bystanders are A-holes.
Side Two: My buddy has been busting his butt all day to fix his Jeep. I am not about to abandoned him to go shoot the bull with folks I don't know. They can come talk check out what's going on if they are interested. (Obviously, I am making an assumption that you were not there alone and that there were others in your group).
Regarding the guy familiar with the Wayalife videos: He may not be the kind of guy who feels comfortable randomly walking up to someone such as Eddie, who is clearly busy, to say hello. I'm not sure I would, in that situation.
PS: I don't have a dog in this fight, just trying to be objective.
