From "Star Trek: Deep Space Nine: Doctor Bashir, I Presume? (#5.16)"
You've never had a child. You don't know what it's like to watch your son... to watch him fall a little further behind every day. You know he's trying, but something's holding him back. You don't know what it's like to stay up every night worrying that maybe, it's your fault; maybe you did something wrong during the pregnancy, or maybe, you weren't careful enough. Or maybe, there's something wrong with you; maybe you, you passed on a genetic defect without even knowing it.
No, this is important. You can condemn us for what we did; you can say it's illegal or immoral or whatever you wanna say. But you have to understand that we didn't do it because we were ashamed. But because you were our son. And we loved you.
