She initially wants you to agree that she really is busy and to comment on how hard it is to have a career and raise a family. Later, she might welcome a suggestion that she consider getting a housekeeper or having the grandparents take the children one evening each week. Think of someone you have recently enjoyed being with. If you reflect on the conversation you had with the person, I suspect you'll find that the two of you agreed on a lot of things you discussed. On the other hand, when things sour, it's often because there is less agreement.
Recognition is another part of what people want.
You recognize a person by smiling and saying hello when you see him. You recognize someone by looking at her when she's talking, by asking questions, by keeping the topic on what she's talking about. You recognize a person by giving him compliments and thank-yous, and pointing out how smart, funny and helpful he is. You recognize with hugs and presents and e-mails. You help make the person feel welcome in your presence.
