I wasn't questioning if your parents were your biological parents, FK. I am surprised you misconstrued it that way. I was talking about believing delusions and believing they are real.
Relax, I didn't take it personally. :) I was responding that I know it can't be a delusion because I have evidence, etc.
But phyisical resmeblence is no proof. I know a couple who married for the second time, one of whom had a 4-year-old daughter and people, not knowing this, would find defnite "resmeblence" of the new husband in that child! Pictures are also no proof. If you are adopted as an infant, you will have infant pictures with your adopted parents. So, evidence can be misleading too.
