We've been feeling it since the first few months of life, when we didn't get what we wanted in our cries of protests, things like, "What do you mean you won't pick up the rattle, Dad, I want it!"
Lo hemos sentido desde los primeros momentos de vida, cuando llorábamos al no conseguir lo que queríamos, cosas como: "¿No vas a recoger la sonaja, papá? ¡La quiero!".
