Seen all over, but started by 
silmaril: when you see this, post a bit of poetry in your own LJ, explanation optional.
Because one actually popped to mind, I'm going to be a sheep:
And now good-morrow to our waking souls,
Which watch not one another out of fear;
For love all love of other sights controls,
And makes one little room an everywhere.
John Donne, "The Good Morrow". These lines were on the bookmarks we had as wedding favors (along with chocolate books that the hotel lost half of, and some of the 1001 origami cranes Chad's sister made us). I wonder if we still have those spare bookmarks?
