When I look at those little cards and letters, it reminds me a lot about past.
It was so easy to write 'forever' but..
when you look back at everything, you will realize that everything changed.
People weren't close to each other anymore, some turn from strangers to best friends.
Some people said 'The people in pictures doesn't change even it reality they do'
That's why pictures are able to capture the happiest moment in life.
It will be tough for us to look back sometimes, knowing that promises and memories have fade.
It's difficult to keep a promise.
Hence, appreciate what you are having now because you will never know what happen next, who will be leaving you or when you are unable to keep your promises anymore.
