"Jugadas de la memoria"

My friend Jesus wrote something that made a huge impression on me. He wrote about his life/impressions 8 years ago, when he just had arrived in Sweden. And he is talking about these meetings/gatherings that just happen once, when you meet a person that makes a big impression on you and you remember even 8 years ago. I had loads of those meetings, just once, one time only. As well as him, sometimes I would meet a person that would make me think a lot, that I would find interesting, and that I would never see again.
