My DD initially showed some interest in it, but as we talked about it, it seemed more like she wanted to press the issue on an equality basis, rather than on the basis of really wanting to serve on the altar, if that makes sense. If she really felt that she wanted to do it for spiritual reasons, I would be trying to "work the priests" (so to speak), but just to make a point? Nah, not worth it.
DS, on the other hand, loves it. He's very reverent, very sincere, very totally opposite how he is any other time.
