No point beating yourself up about this gertrude. I have flown from Sherburn for around 5 years now. Ok, you didn't see the aircraft on final, it is often hard to spot aircraft on final, what runway was in use? 24 is especialy difficult to see aircraft on final. If it was 29, thats not bad but they are still missable. You entered the active, and at that point the aircraft on final has to make the decision to go around or not. Your turning back off the active onto the taxiway is a non starter, I wouldn't even try. What if something goes wrong? Far better a go around than a prop strike or other incident. The instructor or student should have kept there mouths shut in my opinion, especially on a go-around and your take-off which requires alot of concentration. Last thing you want is an insult coming through your headset. Had I been the CFI, I would have been having words with the instructor/student on landing. Not professional, and not becoming of an instructor!
