I’m adding on here in case there are ignorant people who saw this and assumed she was “punishing” him this way;

I have pretty severe ADHD and I won’t notice I’ve done the thing (exhausted someone) until well after, either. She warned him, they went on the date, she did the thing (excitedly talk a lot) and then noticed she’d sucked his soul dry. This is an unfortunately normal event for us. Which is why the warning.
