My wife is the only person I'm nearly totally honest with. I won't say completely honest, but it's pretty close. Far more than I see most people be with their opposites.

Sometimes it hurts her, sometimes I say something and wonder if I should have lied instead, but ultimately I think it makes everything so much healthier between us. If I'm in the middle of something and she's telling me a boring story about shopping for clothes, I'll tell her right out, I'm busy and I don't really care about your clothes shopping. She'll be annoyed but she'll also listen, and doesn't harbor any long-term resentment over it. I don't know that this would work for everyone, but I think it's a good thing to do.

I don't think I have the courage to do this with everyone, though.
