I can't whistle.
Technically, I suppose, I can wrap a present - only not in a presentable manner.
I'd say that I throw darts "like a girl" (if I may be allowed to use that expression). On a related note, my mental arithmetic is very slow. (Mostly right but embarrassingly slow).
I haven't a note in my head and I dance like a drunk killing cockroaches.
On the other hand, I can spread my toes in exactly the same way as I can spread my fingers. I was astonished to learn, whilst on holiday last year (I'm in my forties), that this isn't a common, everyday ability.
