Gerhardt,
I do the same thing with a couple of people I fly with. In fact, I won't fly regularly with anyone unless we can have that sort of relationship.
I have a friend I regularly go on long trips with. We have a couple of rules...
1) If either of us feels something should be pointed out, we'll say it.
2) If decisions have to be made concerning weather etc, we won't fly unless we're both happy about it.
This person is an instructor with way, way more experience than I've got. If she can think that way, maybe everyone else should consider it.
