He informed me, sadly, that the letter was for a previous tenant - R M Long. It was marked 'private and confidential'. Being a nosy sort, I opened it anyway and discovered, to my amused horror, that it was a catalogue for porn. A whole glossy paged tome to wang dang doodles and bouncy breasts. We had titles such as 'Fuk'n Tight Holes', 'Hung House Husbands' and 'Fusxion'. Oh, and my favourite, with the lewdest cover of anything I have ever seen - 'Stoff' (under the eurogay category.)
This is a story to tell around the table at Christmas.
