I'll still always be amazed when I talk to old friends who I talked to every day for a long period of time. Knew all their hopes and dreams. And all of a sudden it just ended. Don't know if they still love the same music they did 3 years ago. Don't know if they still act the same. Don't know if they look different. Don't know if they got a haircut.
One day you talk to that person again and you feel like it's back to normal... But nothing will ever be the same as before.
