Todays post consists of 7 letters. As this is before email, we would expect some of these letters will be actual correspondence with friends. A letter from a friend who no longer lives in the area, a thank you note from Ken for coming to his party, an invite for next year's Barker's Summer Party. One letter has an air of mystery about it. This one is the letter without an address on it, yet it does have a stamp. How did the postman know to deliver it to George and Lynne's? The only explanation would be that the sender address is the same as another going to George and Lynne's that day. Maybe it was Sammy and 'Mantha's invite to the Barker's Summer Party. They made such an impression that they have been invited again, but the Barkers did not know their address. Why they didn't just phone George to find out their address, I don't know.
George wants to look at his wife's bum. This is a woman who seldom wears clothes so why he is grasping at straws to find ways to see her in compromising positions. This is similar to the barge incident. It must be a ritual that he can't let go of. Ever since they were first together, George has always looked at Lynne's bum when she bent down to pick up the post and he just can't let it go. Either that or he had a bad experience with a letter with no address before. He once opened it to find it was an envelope full of razor blades from a disgruntled postman. The postman should know that he should have written an address on the envelope in order to cover his tracks. But maybe his handwriting is so unique that it would have given him away.
