Your friends will know you better in the first minute you meet than your acquaintances will know you in a thousand years.

I’ll stick with you baby for a thousand years.

We have learned nothing in twelve thousand years. (Upon exiting the Lascaux cave, France)

No matter when you had been to this spot before, a thousand years ago or a hundred thousand years ago, or if you came back to it a million years from now, you would see some different things each time, but the scene would be generally the same.
