I get why “taller = older” is embedded deep in our psyche’s somewhere (you’d have to a pretty stupid two-year-old to not pick up on that), but I still feel like adults should be able to override it with conscious thought.
But in this particular case, I doubt Wilson believed the girl was legally allowed to consent on account of her being 6’7". And if he did, that’s actually just stupid - girls usually reach their full height by 14.
