I Can See Thing That Aren't There

Connor was just a normal boy growing up, but that was all before his father died in a terrible car accident. The young boy had witnessed the whole thing and heard the last words of his dear dad as he watched him died from the back seat.
From that day on the boy was miserable, but on one day while sitting out in the garden his father had came up behind him and the two talked.
Now, Connor is 17 and has moved houses with his mom, siblings, and step father.
He's mom just wants the best for him and if moving gets him to stop believing that he's speaking with his father then so be it, but what she doesn't know is that the move was probably the worst for him.
