Well, I think certain things aren't gonna last forever, whether you like it or not.
But, if anyone's religous, I'm pretty sure they believe their ...deity is pretty much immortal.
I think that love, the family kind, and maybe true love, lasts forever. I think that certain beliefs and convictions will last forever and withstand the test of time. And I guess the last thing that will last forever are memories, certain ones anyway. They maybe intangible, but they're still there.
