I'll take more responsibility, not ALL responsibility. But when out with relative newbies, I need to be a little more perceptive, a little more insightful as to how people are functioning. Are they getting in over their heads? Should we shorten the excursion.

As an extreme case, when I was introducing my kids to the otudoors, you can bet I was assuming responsibility then. With more casual acquaintances, I am less involved. An intermediate situation would be working with new members on a SAR operation - you had better be tuned to your mates in that situation.
