Poet: When you give someone your whole heart and she doesn't want it, you cannot take it back. It's gone forever (ie. unrequited love sucks).
You: Holy fuck!!! Now what? It´s not even like I wanted anything!
Friend: Stick by her, if she´s worth it... One day she may get that this shit is for free.
You: Cool! I´ll try that...
