During practice for our school-wide Winter Sing:
Student: "Deck the halls with balls of holly, BLAH BLAH BLAH BLAH BLAH, BLAH BLAH BLAH BLAH!"
Me: "Oh, it's actually, 'fa la la la la', not 'blah blah blah blah blah.'"
I did not try to get into saying "boughs" instead of "balls." You pick your battles.
