Ask Amy: Should I tell my longtime friend who his biological father is? Updated 6:00 AM; Dear Amy: I’m holding on to a longtime family friend’s secret, and it’s very upsetting. My friend “Chris” and I grew up together as kids. We always acted as members of each other’s extended family. We are now middle-aged. Our mothers were friends from kindergarten on, until each of their untimely deaths, when they were in their 50s. I was given a huge burden when my parents told me that Chris has a different father than the man who raised him and who he thought was his father.
