Input: Long story short, my dad has history of issues (addition based mostly) and has been distant from his relatives for a long time. After my parents divorce they stopped communicating with my sister and I (age 11 at the time) and I haven't really seen them since.

Fast forward to recently and my dad is in rehab again and wants to reconnect with his mom who is elderly. I found her info online and sent her a message asking if they would like to meet. They seemed happy and said yes. My dad and I went to a restaurant and met up with my grandmother, aunt, and cousin (who is 22). It was all going well catching up until we were saying goodbye and they kept talking about how important family/blood was. My grandmother made a snarky comment about my mother, who they dislike for leaving my dad for his issues, and "jokingly" implied I was too much like her. Literally talking about how key blood relationships were. Now it's important to note my aunt adopted my cousin years ago when she was a baby, and to my knowledge it was something she knew about. She was only a toddler when I last saw her, but she looks nothing like my aunt/uncle and my dad had told us and never said it was secret. So I commented back that Cousin seemed to be fine despite being adopted, and it was like a bomb went off.  Apparently she was never told? My dad seemed surprised at the reaction too and they left angrily. Was I wrong here?  I probably would never have mentioned it had she not gone on about how important blood ties were.
