The origin of the custom does suggest that the bride's Second shouldn't be the groom's mother, but fear not, the practice of the Second serving as substitute spouse in case the principal drops dead before the ceremony has been abandoned for at least a hundred years if I remember right. Um - perhaps you can find an excitable female optics engineer to have regular chats with?"
