Reading between the lines.

As you know, I think that one of the most irritating things Michael has ever said to Liz was "absence makes the heart go wander" when she was desperate for reassurance about her long-distance pseudo-relationship with Paul. The problem is that Mike might actually know what he was talking about owing to his experiences this summer.

This is because hindsight tends to make the postal clerk who told Mike to read between the lines about how she didn't write might be on to something after all. This is because not having Mike in her face all the time might have opened Martha's eyes to all the stuff she had to give up for him: her friends, her peace of mind, her self-esteem and all of the other things that get in the way of Mike achieving the end game of seeing her naked. People tried to let him down easy by telling him that she can't find the words to express herself but it might be that what she wants to express is that she's starting to feel less like a person and more like an accessory to his ego. When even he himself starts to question an excuse that flatters him, it might be a warning sign that he's slowly being friend-zoned.
