Highlighters

Dd8 has discovered the joy of highlighter markers. She is highlighting words in her music theory book, pieces of paper she's written on, and anything else with printed words which she thinks I won't mind her defacing. The worst is when she makes me read what she's highlighted--just the highlighted words and not anything un-highlighted. She giggles and thinks it is so funny. I don't (except that I think her pleasure in it is cute), and I keep coming up with excuses to not listen/read her highlighting.
