When Ethan returned home, he thought he would have to spend quite a bit of time to explain things to his parents. However, they weren't at home, but they had left a note for him. Apparently, Hannah had already explained things to them.
"Ethan, to think that you were already this old… I think I missed the opportunity to teach how to grab a girl's heart. Still, you are my son, so you probably can do that without my lessons. Go get her, tiger."
"Don't overdo it trying to show off in the front of the girl you like, Ethan. Women like men who have heart, but they don't like idiots who can only show off and are all talk."
