I may well have missed the point of this one - instructions were conspicuous by their absinthe, as my old grandma used to say - but this seems a little on the boring side. Correction - a lot on the boring side. Pat (who's a smug little git, let's face it) has loads of letters to deliver - only he doesn't deliver them in the sensible way, by looking at the addresses, sorting them into piles and then bunging them in the letter boxes street by street.
Oh no. He merely walks around his neighbourhood, waiting for enormous black arrows to appear next to the appropriate house. Very efficient. (At least it explains why my post always takes days to arrive!) Pat also has loads of errands to run for his oddly lazy customers, which consumes even more time. That seems to be about it for this game, so out the window it goes.
