One of the things I looked forward to about being a parent was answering questions about the world. What is the sun? Why is the sky blue, etc. And, I figured, even if I couldn’t answer my daughter’s questions I could look the answers up on the internet and then translate the explanations very lucidly.
This has hardly ever worked in practise. Today’s question: why are the leaves of a Savoy cabbage so wrinkled? ‘Uh . . . water retention?’ I guessed, before looking online and not finding an answer. Any botanists out there want to answer?
