This work demonstrates how, when one experience ends, it opens the door for another to begin. It follows two best friends as they say goodbye to snowmen, and hello to stomping in puddles. They say goodbye to long walks, butterflies, and the sun – and hello to long evening talks, fireflies, and the stars. The hardest goodbye of all comes when one of the friends has to move away – but even the hardest days come to an end, and you never know what tomorrow will bring.
