A bouquet of red pens and orange highlighters

Right now, I wish somebody would had sent me a bouquet of red pen and orange highlighters.
Yeah, I know, you'd think it's just another You've Got Mail tribute post, but, no, I really need some new stuff. It seems that I could study better by writing side notes with the red pens and highlighting important stuff on the reading materials with the orange lighters. Better go to the "market" now...
