DEAR ABBY: My husband and I are both Caucasian. Recently, we adopted a beautiful mixed-race baby girl. She's Vietnamese, African-American and Hispanic. She is not even 4 months old, and already we have experienced some negative comments from strangers.

Where we live is progressive and open-minded, and I'm not so much concerned about our neighborhood or schools. But I'm no dummy. I know we're going to encounter people who have "questions" or unwarranted "opinions" (to put it nicely).

I'm not trying to educate those who choose to remain ignorant, nor reason with the unreasonable, or even explain our family and our choices. I just want a quick, witty response that tells people their not-so-nice comments are unwelcome and, to put it frankly, back off. Any suggestion?

DEAR OPEN-MINDED: According to the 2010 census, 9 million Americans (2.9 percent of the population) are multiracial. It also showed that the number of people who reported multiple races grew by a larger percentage than those reporting a single race.

Frankly, I don't think you should say anything "witty" to a bigot. Just smile and say, "It's the wave of the future. Get used to it."

DEAR ABBY: When my in-laws come for dinner, they ask what they can bring. I always say "absolutely nothing," but they bring dessert or a bottle of wine, and then take the uneaten dessert or uncorked bottles of wine home with them.

What's the rule of etiquette when someone brings items to a party?

DEAR WONDERING: When guests bring something to their hostess - a bottle of wine or dessert - it is considered a gift. For guests to commandeer the leftovers without them having been offered is poor manners.
