Court House libraries deal with a lot of paternity cases, especially in counties where the DAs aggressively collect child support. All the sad stories came back to me yesterday when I was walking down Flatbush and saw a van with this advertisement painted on its rear window: "Does he really have his father's eyes? Call 4DNA. Child Support, Immigration, Criminal Court." Somehow all the red roses being sold by the street vendors appeared terribly poignant. Love sure can go wrong.
