Answer: When Johnny said that to him, he meant for him to stay innocent. He meant for Ponyboy not to go down a bad path like many of the other greasers did. It was a reference to the Robert Frost poem "Stay Gold". Ponyboy had recited the poem to Johnny when they were hiding out at the Windrixville church. In one line of the poem, it had said "Nothing gold can stay" meaning that all good things must come to an end. So he was telling him to stay gold or stay good. So if you think about it he was telling Ponyboy not to change.
Answer: My favorite building personally is The World Trade Center (previously known as the Twin Towers) What I like about it so much is 2 things, 1. It has a lot of history behind it, it was a terrorized attack led by Osama bin Laden, the leader of the attacks on Pentagon too, and my second thing is the height, 1,776, and if you didn't know, they specifically done this because The Declaration of Independence was signed on August 2, 1776. But in all, The World Trade Center is a really cool place.
