I have always encouraged children to be adventurous and explore what they love. This time, the 15-year-old brother discovered that an influencer used hydro-dripping to dye trainers. He proposed to dye trainers with his 10-year-old brother and ‘instructed’ me to buy spray paints of multiple colours. I let the two brothers do the shoe-dyeing experiments, not minding making the home dirty. I just observed and offered help on the side, while inducing them to accept the smell of spray paints, instead of complaining. When dyeing the third pair of trainers, the elder brother had mastered the timing and successfully turned the trainers into a ‘chic product’. He also clearly instructed his brother on when to control and when to release the spray so that he could make a pair of ‘chic product’ too. Children have their own ways of communicating with each other, learning and teaching. I only have to provide the environment for them.
