Forgot My Grocery List Again

I walked out of the grocery store without my milk and eggs again today. I know it's just a simple list, but I've been forgetting it more often lately. So one day last week, after getting frustrated with myself for the hundredth time, I decided to write 'milk' on an old receipt so I wouldn't forget. Now every time I see that crumpled-up piece of paper in my bag, I feel a bit silly and guilty, but it does work sometimes.
