At the end of the day we're all alone. Surrounded by people all around, some of whom love us, some of whom care for us, some of whom like us, some of whom dislike us, and most of whom dont even know about our existence or couldnt care less. Yet, there is no one, no one who is going to be there forever.
People come, people go. A relationship that was so important yesterday means nothing today. Memories fade away, life moves on. And we carry on.
And we can only be happy if we learn how to not expect. Then everything you get becomes a blessing. Its not so easy and its not so tough. Its however so easy to let go of anger, disappointment when you learn to not expect.
