I have been on both sides of this. Admittedly, mostly on the receiving end. I think a lot is learned from both parties - by having a probably less experienced pilot ask you questions you question yourself and your actions. By being flown by people with a lot more experience, you learn that nothing terrible will happen if you push the envelope a little bit more. Unlike instruction, you are benefitting from the realities of a flight, rather than an exercise. Roll on the day when I can give again!
