Our children grow up very quickly: yesterday my son was a sweet and affectionate little boy, and tomorrow he will become a young man who shaves, speaks in low voice and dodges my hugs and kisses. And between yesterday and tomorrow there is today - a strange and difficult period called transitional age. And today my son is very fragile, very scared, not fully understanding what is happening to him and therefore aggressive. And I want to capture and remember the changes that occur every day in the body and psyche of my 13-year-old boy, I want to understand how he turns into a man.
