No worries, life would be rather crap if we all had the same experiences.
Sometimes a source of confusion, depending on your age and previous experience, or how someone puts it across to someone else.
Retired Military - Someone who could have retired at 40 with a Government Pension.
Retired Police Officer - Someone who retired after ( I think ) 25 years with a Government Pension.
Same with Firemen and a whole load of others.
All retired, in receipt of a Government Pension, and not old enough to qualify for a retirement visa / extension in Thailand.
