When they became boyfriend and girlfriend, he gave her a pen of red ink which represented the love he felt for her. With that pen they wrote a lot of stories about the dates they had had, the kisses they had shared, the fights and the make ups they had had, the gifts they had given each other...
They wrote so many stories with that pen, that one day, the pen ran out of ink, and they only thing left from all the love they had for each other was the stories they had written with that pen of red ink; but when re-read, the stories looked like as if they were written with a regular black ink.
The end.
