Hahahaha, deja vu, you don't post very often but when you do....absolute gold..!
deckchair - good luck with your instructing (sincerely). Perhaps a more magnanimous attitude would be advisable. You can learn a lot from some of the seasoned professionals on this site. Even if the delivery of their advice can at times be a bit more abrasive than what the younger generation seems to be able to tolerate these days, it is worth taking on board. Instructing can be a tough gig at times (as can other flying jobs). Develop a thicker skin, roll with the punches, you'll be fine.
