We were on our way to the library. The little one in the stroller and the big sis skipping by. We had to cross a school. There were cars coming and going out of the school. Taking this as a good opportunity, I showed big sis the indicators and explained how, a left indicator means the car is going to turn left into the school and hence we need to wait for them. She took all this in and even noticed that cars that don't have the indicators on, would travel straight. Then came the masterpiece..
"Mummy, how nice it would have been if we had indicators on our butts!!"
