You have moths in your logic (cf. 
https://en.wikipedia.org/wiki/Grace_Hopper):
   Moth, the first:
       When asked for unexpected permission, "Just say NO"
       [If doubtful, then dirty ;]
   Moth, the second:
       What if I had been logged in as root?

It was only a WAG (wild a????? guess) that sudo might be appropriate ;}

*ROFL*

CAVEAT LECTORS:
I have a history of problems asking questions on this forum:
   1. I prefer to ask narrowly focused questions.
      That gets response "Tell us more".
   2. If my original question has details, the responses I get can be
      summed up by somebody's signature tag line -"Universal advice --
      DON'T do that". [should that *ROFL* or "weep weep"?]

P.S.    You have been saved from a plethora of bad puns.
P.P.S.  I've read several articles on "how to ask questions".
         None address my balancing act quandary ;/

*P.P.P.S.*
A definite thank you to all who attempt to answer my questions ;)
