South Africa, April 8 -- Let me explain both.

A few months ago, I began stopping at our nearby Woolies on the way home from school pickup. My son figured it out quickly - the direction we turn from the school gate, where I park, the little toddler trolleys at the entrance, and the fact that despite walking in there for spinach, he'll get a snack every time. Then there's the first gondola when you walk in: blueberry muffins. His favourite thing in the world. Now, every pickup day, there's a small but very determined three-year-old pointing left when I turn right, whispering "this way Mommy, let's go shop". Woolies became easy to think of and easy to find (for him anyway) and they earned that entirely by accident.

Now for the other story....
