Seriously, it's getting old.
If you're curious, this is my opinion on it (basically, there is no such thing): http://www.girlsaskguys.com/relationships/a7737-the-friendzone-does-not-exist-the-way-you-think-it-does
It's a fallacy, to think you can manipulate yourself out of the friendzone. You can't. It just happens if it's meant to be.
There are also couples that started as friends. Those were meant to be, so they eventually evolved into a couple."
