We live in the country. (DH moved here from a village but he traveled in New Zealand at one point!!)
Out for a walk the other day and he mentioned about how some sheep have black heads but white wool. Somehow in the course of the conversation it turned out he'd never actually seen a black sheep. There were none in the fields around us so ended up walking a bit out of our way until I could find some to show him!
Is this a bit like not realising Narwhals are real!
