I think you should just wear it. Nobody’s really going to care one way or the other, or if people ask you about it, just say you used to wear it in your old parish and you’re more comfortable with it.
Who knows, other people may start doing it, too! When I started going up to Communion with my hands pressed together (the way we were taught), I was the only one doing it in my parish. Now almost half the people do it, and fewer and fewer are taking Communion in the hand.
My family and I put our hands behind our backs (if we’re not holding a brother), so that Father or the minister of communion can’t possibly be confused by our hands.
