I won't say which two people on these forums I would have expected as prime candidates to be your "problem child."
Generally you are more likely to find 13 to 15 year olds that will decide they have to know more than the instructors...
Sometimes you get it with adults... especially full scale pilots who are GOOD and older than the instructor. (crop dusters and fighter pilots are worst... You can't tell them
ANYTHING 
)
