I was reading another book, and it was talking about how Harry secretly wanted his kids to be in a different house instead of living in his shadow and this came to me:

Lily Luna is sorted into Slytherin because growing up with Harry and Ginny as parents, George and Ron as uncles and Arthur as a granddad has taught her to stand up for what she believes in. 

And how to unscrew the chandeliers just right.

She is so upset and scared about what her parents will think and sends an owl first thing in the morning to her parents asking them to not be mad at her. 

The next day at breakfast she receives a howler. She is so scared and is halfway to the door before her parents voices are telling her how proud they are.
