I worked as a postman for a bit. I'd wake up at 0430, make a short commute, then sort letters into street/house number order for something like 3 hours. After the first few days this became mindnumbingly dull. It was obvious 90% of what I was about to deliver would go straight in the bin so all this drudgery wad largely pointless. For a while I worked in a pretty rough area (by UK standards, admittedly nowhere in the UK is really that dangerous compared to much of the world), and on several occasions I was harassed by members of the public. Though later I worked in a much nicer area and people were nice to me.

I suspect the main thing about the story isn't how great it is to be a mailman, but how great it is to be good at people. I work from home and live in quite a nice community, but I only know a handful of people. This is basically because unless I have a common interest with someone I don't really have anything to say for myself. Clearly not something that afflicts Floyd!
