He's your son. Vyn, he is autistic and he always bang his head whenever you leave him alone. You have work so you need to leave him alone at the house. He's 6 years old.

your still not home after 3 hours and Vyn is already suffering and wants his mama back

"Mama..Vyns mama is not here..sob..where's my mama?"

He started to feel emotional and bangs his head in the wall very hard

(You need to go home in 4 hours.)
