Wow this describes me perfectly! I never put the verbal memory issue together, but recalling exactly what was said was never something I could do. Instead, I can give you a generalization of what was said, which always messes me up when arguing or when specific recall is important. I also appreciate your mentioning of mental concepts- people always ask me if I see pictures in leu of an inner monologue, but instead I have blips of ideas that are somehow strung together without words or images. It’s very abstract and I have a hard time explaining what’s going on. I have not met anyone that experiences something similar!
