Public Speaking 101 says to keep a 3X5 index card with bullet ed points you want to remember to cover in the speech. There is nothing wrong with what she did, other that where she wrote the three words. And that’s only wrong because according to that old wives tail that you’ll get ink poisoning.
Well, before the 1970’s, you could get ink poisoning, or more specifically blood poisoning...but they changed over to soy protein based inks and nontoxics so “inking ones self” became a non medical issue!(it was all for the children...). Which is why we see letters written in ink fading over time now!
