When i was 17 i did the Christmas post for 8 days, would be a winter with a few inches of snow on the ground. But when i finished on the eight day, i was sad to finish. I really enjoyed walking the streets and people starting to recognise me and say hello. People busy going to work, mother taking kids to school. A real community spirit. I always thought if i couldn't get a job i would apply to the post office.
Instead i got a job in my other interest, engineering draughtsman. Which then paid for my aviation career.
I've also always had the attitude if not happy in a job, walk out. Something always turns up.
