WASHINGTON--First Lady Michelle Obama seemed a bit ambivalent about Valentine's Day when the subject came up last week during a lunch with 10 print reporters, but she did have advice when she was asked about helping a marriage survive

On Valentine's Day itself, Mrs. Obama said, " I was like I don't really care."

On the subject of marriage, Mrs. Obama said, "You know that's a good question. I think a lot of laughing. I think in our house we don't take ourselves too seriously, and laughter is the best form of unity I think in a marriage. So we still find ways to have fun together, and a lot of it is private and personal. But we keep each other smiling, and that's good."
