In my parish, before the advent of altar girls the boys all served eagerly and would argue over whose turn it was, argue because they wanted to be the ones. Since we started altar girls only one boy is positive and volunteers to take the place of his reluctant fellows. And only a couple of the girls do it eagerly though none of the girls try to argue their way out of it on Sunday as the boys do. There is nothing distinguishing about it any more.
You know how I feel about this issue!
