Rocket Tree

When I was in primary school, I drew a big tree on a chalkboard to the best of my ability. The teacher walked past, looking at the picture upside down & said "Wow that's great Matt! That's an excellent rocket!" confused until I realised she'd mistook the puffy leaves on the tree for smoke when she saw it from her perspective .... I won a special award for that "Rocket" and have subsequently drawn my trees without leaves... ;Puerto
