If Harry's Parents Really Could Be Alive Or If Harry Had A Family
After a week at the Burrow they went back to Godrics Hollow bringing Harry with them. The 10th of August Lily sat eating her breakfast while the men were out playing quidditch and the twins were getting their godmothers. Suddenly she heard a knocking on the window and saw an owl waiting outside, she opened the window and let in the owl who carried a letter for her.
Dear Mrs. Potter.
Our Divination teacher, Prof. Trelawney, has retired to start a carrier in writing books. We hope that on September 1st you will join our staff as a divination teacher. I have talked with the Minister of Magic and he has allowed you to take this job since he has decided on letting the world know of your return soon.

Of course she would take the job! She found a piece of parchment and scribbled down a letter to Dumbledore and sent it with the awaiting owl.
At the same time on the Godric Hollow Quidditch Pitch.
The four soared around in the air as four owls came flying towards them. They landed on the ground and received a letter each from the respective owls. Harry's letter was the normal letter including a list of purchases and some sheets with new rules since he was the Gryffindor 6th year prefect with Hermione. In Remus' letter there just said what he would teach the students, he was the Defence against the Dark Arts teacher beginning his third year teaching. Sirius' was an wish of him accompanying Hagrid in Care of Magical Creatures and taking over the job when Hagrid was visiting the Giants. James got a letter as well.
Dear Mr. Potter.
As our Potions teacher, Severus Snape, is on a mission on my request I wish for you to teach in your place, since in your days in school you were a fine potions student. I will await your owl.

At the same time in the Evans Mansion 1.
Violet was awaiting her Goddaughter Cassie when an owl flew in the open balcony door. Violet untied the letter and opened it.
Dear Miss Evans.
Our Astronomy professor is retiring after Christmas and I wish for you to join him in his classes this period and take over the class after Christmas. I know you were an excellent Astronomy student and I hope you will accept. I also wish for you and your two sisters, Lily and Dahlia, to help out in the Muggle studies class as you grew up in a muggle home. I will await your owl.

At the same time in the Evans Mansion 2.
Dahlia was leaving the house with Cassie and Luna as an owl came fluttering down from the sky carrying a letter. She stopped and relieved the owl of its burden.
Dear Miss Evans.
I am starting a new branch of teaching in the Muggle Studies class. There the students will learn muggle history, mathematics, geographies and so on. I wish for you to teach this class as well as joining in on the normal Muggle studies class with your two sisters Lily and Violet as you three grew up in a muggle home. I will await your response.
