I wrote a blogging platform around 3.5yrs back in PHP. My friend uses that, and apparently wants me to update the code. To which I refused saying that I am too busy. But the real reason is that it is one of the purest form of cancerous shit I ever wrote. I can't even look at that code now. Its like abandoning your own child, because it is too ugly... Here's a snapshot of the code, I don't even know what this does anymore..

Moral: Don't give your code to your friend no matter how shitty it is, you will end up providing lifetime support for it.
