It's rude to give unwanted advice.
Jen is explaining to Bill how her husband has been having some problems in the bedroom lately.
Bill wants to respond to Jen's statement.
Bill tells Jen that he understands it's tough and hopes that they get through it at some point.
Bill tells Jen that if only she dressed more provocatively that her husband might perform better in that area.
Jen feels supported by her friend and happy that she has a person she can tell her problems to.
Jen is disturbed that Bill would even think of such things and is insulted at his insinuation that it's her fault for her husband's problem.
