Just like when my nephew, Saehyun was younger than now, we put stickers on the mirror. But this time, it was for photography. Sae-hyun's generation is a generation that cannot imagine life without smartphones. Smartphones were already in the world when he was born and he experienced with them from the very first moments of his life. The expression of emotions I feel for him and the perception of the world will be different from mine. It still remains a mystery to me.
