Good song for this???

A song when I am looking back at all the good times I have had with a best friend and I love this best friend very much. But I have kinda lost this friend and I kinda miss all the memories. Me and my best friend don't hate eachother but we just grew kinda apart. But she was the bestest friend I have ever had. But I need a song that you would hear if this was in a movie or something where I just think of all the good times and sigh and realize that they are over. And I want a song where its NOT sad or slow or boring or very old. Please. Something that is happy but sad at the same time kinda. I hate rap so no rap. I want something thats NOT silly or girly or stupid. I want something thats like punk. Like NOFX and Alkaline Trio.
