Some friendships, no matter how hard you try, never recover the joy they once had. But if you feel pain of regret or remorse when you think about a lost friend and do nothing about it, you'll never know what might have been.

I think I got a lot of friends but I don’t hear from them. What's another night all alone when you're spending every day on your own?

But thoughts they change, and times they rearrange; I don't know who you are anymore.

Some friendships die because they aren't moving forward. They die from stagnation or plain neglect. You promised to call but didn't. You knew it was your friend's birthday, but were too busy to celebrate. When we're busy, we only do what comes easy, and even good friendships aren't always easy. Lack of attention and concern is sure to cause a rift. And when it does, it almost always catches us off guard, when we least expect it or can least handle it: when we're going through stressful times that make us less attentive and less able to respond—which is what caused the neglect to begin with. That's why it can seem that the best friendships break precisely when we need them the most.

Even with the best intentions, growing apart might just be an inevitable part of growing up. It’s no one’s fault, so there’s nothing to feel guilty about. It’s just the way things are.

Remembering all our memories, and it’s times like these that I miss you most, remembering when we were so close.

And I wonder where the friendship went. What about the days and the memories we spent? Now it feels like I’m being replaced. Now it feels like I don’t know you.

And slowly as the days go by, you lose friends you never thought you would.

I saw you today and realized how far apart we’ve grown. I know I should talk to you and ask you how you’re doing. And I really wish I could. But it’s just occurred to me that we’re strangers now. You don’t know me anymore, much less want to, and it’s okay that you’ve moved on. I know that everything’s different now. I’ve been staying strong.

Some say that time changes. Best friends can become strangers.

Lately you haven't been a good friend and I'm kinda tired of staying here waiting for my best friend to pick up her phone when I'm crying. It's not what I expected my best friend to be like.

The biggest mistake you can make is to drift from someone you once had the time of your life with.

To forget a friend is sad. Not everyone has had a real friend.
