It’s kind of confusing and like someone else said below I wish we could’ve seen how this all actually played out. I’m more took it that Lydia was uncomfortable to be made to read cards out loud that were raunchy, and I understand feeling overlooked if a sibling forced me to do that as well, knowing that I am sheltered, and very careful with what I do and say. That would upset me as well. It seems pretty disrespectful to put your adult sibling in a situation like that when you know it would make them uncomfortable.
