Is honesty good for relationship?

A man arrives back home from work. The woman immediately notices he isn’t well (women have this sense) and tries to cheer him up in a womanly way. That is, instead of offering passionate sex and a relaxing massage, she first needs to figure out what’s wrong.

W: how was your day, dear?
M: (groans, while turning the TV on): crap.
W: (being sympathetic): Why? What happened?

Now the man must decide if he is going to be honest (as they made a deal that honesty was above all), or should fake honesty to keep the peace. He decides to be honest.

M: I really don’t feel like talking. Can I just watch football quietly? We can talk tomorrow.

Now the woman, understandably, feels rejected and hurt. She, as well, can be honest, and express her true feelings, or try to keep the peace. Following her own mantra, she chooses honesty.

W: it really irritates me when you come home, turn on the TV and don’t want to talk. Why don’t you want to talk to me?

The man, once again, is facing the same dilemma, but still trying to follow their agreement to be honest.

M: Why don’t we just have sex now? I really don’t feel like talking.

The rest of the evening is easy to imagine. So what went wrong? After all both side fulfilled their agreement to be as honest as possible. However, as long as at least one of them is capable of feeling hurt, rejected or insulted a balance between honesty and keeping the peace should be struck. Otherwise, when honesty wins, relationship will lose.
