One day, I accompanied my daughter as usual to paint freely with watercolours; anything is fine, as long as she is happy. Just like working on my own, I taught my daughter to place the tools in an orderly manner before starting. I didn’t help her this time. She put the sketch book, cup, towel and painting palette by herself. She squeezed the paint in the middle of a grid, leaving a grid between the two colours to mix the paints. She then happily drew some lines at will. To her, the brush-washing water was more attractive. She used the brush-washing water for lighter colours and water drops. I asked her to use thick colour dots on the water drops to see the Haboku (splashing) effect and the flow of colours. She was excited for a while. After that, she confidently said to me, ‘Dad, I teach you to paint!’
