Children’s book set entirely in a rural setting at night. A mother mouse guides her child mouse through grass and vegetation — perhaps a meadow — and I think I remember berries in the illustration. I think she teaches/explains her surroundings to the child mouse as they go. At some point, they encounter a road, and the child mouse feels its cold, hard, unfamiliar texture. I think the mother mouse tells him that the road is dangerous. I was reading this book in the late 80s or early 90s.
