What do you say when finding out someone is pregnant? No, you don't say, "It looks like you've put on a few extra pounds" -- you say, "Congratulations!"
And what do you say when viewing the precious new addition or a picture of the beloved for the first time? You exclaim, "What a beautiful baby!"
But what of the child is rather "plain" or just "plain ugly"? Oops, did I say that?
