Is okay to be obsessed with Harry Potter?

[Savious Aquitaine]

There's nothing wrong with it, but just remember to obsess in moderation. Don't obsess to the point that you forget about everything else. Real life, unfortunately, is not like Harry Potter. There are no spells available in the real world that will pay the bills, get you a job, or write those exams in school. Don't let it take over your life. Besides that, continue to love HP because that's what makes you happy.

EDIT: If you see that your friend is interested in the conversation, don't be afraid to talk to her more about it. This can become another interest that binds you two together. Just make sure not to overwhelm her too much. It's understandable that you would be excitable about something you're passionate about, but remember not too overdo it and go 'omgomgomgomg' all over her.
