It's true. Pictures kept in magnetic photo albums turn yellow over time. And get age spots, like the people in them. This is especially sad when the quality and quantity of your old photos is poor to begin with. But, this isn't a lesson on acid free scrapbooking or making sure you take lots of pictures. Pictures are nice whether they are well preserved or not. But, they aren't really necessary at all. Like Longfellow said,
"The heart hath its own memory, like the mind, and in it are enshrined the precious keepsakes"
Today my heart is full of precious memories... I love you baby girl!
