I kind of lost contacts with Shirin and Shapla over the recent years.Yet, the last time I was on skype with Shompa, she warmly invited to visit her place. She even said I could work on higher studies there. She has recently started working on masters studies in computer science. And I admire her because it looks like she left no stones unturned. She has to be the person she is because otherwise she could never have been the friend I wanted in her. With that, I close the chapter of this little ebook, having the thought of her warm invitation in mind.
