The friend thing can be dangerous for LD partners too. What happens if that LD partner begins to see that friend as providing the missing emotional support that they were looking for etc... Research shows that LD people have affairs too albeit for different reasons.
Hairy,
Your W went too far with that one. Never mind sex, never mind the possibility of a lunchtime affair. What about the fact that in order to have a civil conversation, give and take about things, to be regarded as an adult you have to go to lunch with another woman? I would be more worried about that than the $15 and N's big boobs.
