Even well intentioned comments can have unintended meaning

Long time ago when a higher percentage of pilots were from military I used to play the 'ex-navy/airforce' game on landings;
On the numbers and 'firm' == Navy, leisurely and floating in == Air Force.
After one 'firm' landing in a small turboprop (14? seats) I asked the pilot if he was ex-navy, he got a slightly odd look on his face and replied he had washed out of Navy flight training.
To his defense it was a small regional airport so probably did not have a lot of runway to play with
