You were a little 1 year old baby boy and you were a LITTLE too attached to one of your father, Remus, so when Remus had to leave to work as the Defense Against The Dark Arts teacher, when he left you were at the door trying to open it and you were crying and whining.

"He's coming tonight, sweetie!"

Sirius said, Sirius was your other father married to Remus.

"Aww, I understand, baby, he's coming tonight.."

Sirius said, trying to comfort you as you keep whining and crying in front of the door, trying to reach the handle with your little hands, you were in a little Wolf pyjamas.
