That's true even if it's just passive. I remember working in a kindergarten and there was this adorable, timid and shy girl who never really spoke to any of the adults. I was in charge of the art room she often spent her time there, quietly drawing something. We didn't often interact but I let her draw in peace and never forced her to interact with me. When I announced that I was leaving the kindergarten her mum approached me cause the girl wanted me to write into her friendship book. I did my best to draw a nice Chi cat into the book
