I've never been a person who writes in the margins of her books. The extent of my interaction with a book is usually reading it. Occasionally, I will actually make a recipe or pattern found in a book. Making notes in the book hasn't even been a temptation until recently.
As much as I hate to admit it, my memory skills have taken a nosedive. I can remember useless trivia like who starred in a certain movie, but I'm having trouble recalling whether I made a certain recipe. I've prepared the same bad recipe several times, only remembering as I eat it that I didn't like it the first time. Clearly, I need to start making notes!
The funny thing is that I feel bad about writing in my books. Perhaps it is because I have been a library gal for so long that I don't believe the books are truly mine. Maybe it points to a bigger problem. I experience the same hesitation when I dig in my backyard or hammer a nail in the wall. It's like I'm waiting for someone to give me permission.
To get over myself in this case, I am trying to convince myself that the next owner of my cookbooks may benefit from my notes. Who knows -- maybe some historian will unearth my copy of the Fix-it And Forget-it Cookbook and learn something about how working women fed their families in 2009 :-).
