This is what will happen if Voldemort was never there and Harry's parents were still alive and well.
A typical day in the life of Harry Potter at Hogwarts:
Breakfast: Everyone is happy and eat peacefully.
Snapes Class: Snape loves everyone including Harry Potter
Dinner: Everyone is happy and eats peacefully.
Sleep: Everyone is not scared because they know there is no terror of Voldemort
Other Stuff: Draco likes Harry and Harry has no enemies.
BORING! VOLDEMORT…LIVE ON!
