Where is the School Bus?

We were playing with a puzzle at home before we left for a gathering at Jalan Tiga today. When we came back home, I realised one of the vehicles was missing from the puzzle. "Thaleia, where is the school bus?" To my surprise, she walked straight to her push walker and picked up a piece of chunky wood..the School Bus!! I was totally not expecting and answer to my question. She remembered where she placed the School Bus even after 6 hours. Gee..her memory has surpassed mine.
