What are some of your pet peeves? Some of mine are even numbers of food ie: even numbers of ice cubes, even number of bites. My grocery list is written according to store aisle with unit prices and unit prices after coupons or store card oh did I mention it's highlighted in 2 different colors? Takes me all day & I love it! My daughter & I are compulsive list makers. She once read a book written by an author who is a genius and he attributed part of his success to listing! Really validates my habits!
