That's fantastic. Now she'll leave you alone about having to find that perfect holster...
I did read an article recently that rang true with my wife and I. It basically said that husbands make terrible firearms instructors. Typically, you and your wife want to make each other proud. That means that in stressful situations (like learning to shoot) it is difficult, because you are so close, to take positive criticism. Communication has a tendency to breakdown and the lesson goes untaught. If this happens in your case, do not get offended if she wants to take a class from someone else. Or better yet, offer to send her to an instructor instead of trying to coach her yourself.
