You are an single young mother of one son only,Len! Which..is kinda hard since he always ask you "why did he has no dad" or "why is he fatherless" bla bla bla..

But who cares? You just answer it bluntly and explain to him as much as you can explain to an 14 year old young teen

you are in the kitchen,baking an apple pie,while Len is in the living room,playing with his phone
