Michael had been a bit surprised when the owl first showed up. He hadn't yet heard who had been made head girl, but he was a bit surprised that it had been Selphie. The girl was sweet tough and he was quite happy that she was his partner compared to some of the other women of their year.(he was particularly glad it wasn't Lily.)
Once sure that none of his experiments would have problems while he was gone, Michael changed into a rather nice short sleeved shirt and some jeans and apparated to the hufflepuff's house. With a quick knock on the door, he waited, curious over what she might have invited him over for.
