Been there as well,
When on a check ride for my CPL, many, many moons ago, with an infamously pedantic scottish examiner, who was ex RAF javelins, I forgot to raise the gear on my missed approach from a PFL.
Said examiner was looking out of the window pointing out where his wife was born as I struggled to understand why the climb rate was so poor! A glance at the gear indicator revealed a smugly glowing set of three greens.
After raising the gear, dramatically improving the normally spectacularly poor climb performance of the Arrow, the infamously pedantic examiner looked over at me, smiled and winked!
Proper examiner, I learnt from that!
No one is perfect and we all make mistakes IMVHO.
