This might sound a bit daft. But recently, we found out that my dmum was adopted. She's known for over 30 years but decided to keep it secret until both of her adopted parents (my grandparents) were gone.
I was very very close with her parents, my grandparents. But after finding out that they were not her 'blood' parents, I feel somewhat gutted. I know, it's ridiculous, as they were the most amazing caring people, and still my family. But I feel like I've lost a 'bond' with them.
