In the summer they wear shorts and meander up where one of the lay distributors will lay a Host in their hand and they mechanically shove It into their mouth while singing the "communion hymn" which is taken out of a Protestant hymnal.
Nobody hangs back in the pew because everybody is in possession of a soul recently cleansed of sin through the giving of a good confession and receiving absolution.
Don't blame the Protestants for the lousy hymns in Catholic churches. As a convert, I relish the rare old Protestant hymn when I come across them in a Catholic church -- it is much better and more reverent than the usual saccharine bromides that constitute modern Catholic music, e.g., "Gifts of Finest Wheat", "On Eagles' Wings", etc., etc.
