Lutheran eternity, too, so don't think you can slip in between the time other Protestant eternity ends and the time Lutheran eternity ends.
(My father-in-law, upon hearing Lutherans say the Lord's Prayer, decided that eternity must last longer for Lutherans than for other Protestants, because the Lutheran version of the very last bit is "forever and ever amen," as opposed to Calvinists etc. who say, "now and forever amen" or just plain "forever amen." We have no word as yet on how long eternity lasts for non-Protestants, although if the wall goop continues at this rate, we may well find out.)
Friends don't let friends wallpaper anything. Ever. Because wallpaper is evil evil evil. I theorized this before, but now I know.
