Performing Magic for Friends and Family

Hey everyone! I was wondering how friends and family react when you suddenly start doing magic. They're usually your first audience, and the toughest to face because they know you best, so they see you and treat you differently than a typical audience.

If you suddenly want to show your friends an effect, even in a casual, relaxed way, do they still take you seriously afterward? Or do they look at you differently?

Thanks!
