Thank you for this opportunity; I would happily accept it. While I would love to give a two weeks notice to my current employers, they have agreed to allow me to leave early. I simply must finish out the week as scheduled before I can properly move in. If there are no objections to that, I will arrive early Sunday morning.
Again, I thank you for this opportunity and I look forward to representing the staff of Hogwarts School of Witchcraft and Wizardry.
