Mystery Photos

Once one of my best friends whose name is Nick made a party. It was his birthday party. It wasn't so crowdly about fifteen persons. It was very funny. There was Agatha. She adores photograph. She has a professional digital camera, but she is not a professional. It is her hobby. And she took her camera on the party. And we shot a lot. After several days Agatha printed a part of these photos at the best online photo service how she call it. She always printed her photos only there. Then she came to me and showed photos from the party. Photos were really great. But I mentioned some strange thing on it. There was unfamiliar face for me on all photos. It was a man and I don't remember that he was on the party. I asked Agatha, she said she doesn't know him too. She said that probably he is Nick's colleague. And she said that I don't remember him, because I was drunk. She thought she joked. Next day I visited Nick. I showed him photos and ask about this man. But he said that he is not his colleague and he doesn't know this man. It was unbelievable, everybody didn't know this guy. It was a mystic. Next weekend we had a party again. Agatha took the camera and we photographed. After printing photos at this photo service again I looked at photos and I was very surprise. This unknown guy was on photos again. But I exactly remember that he wasn't there. He was at all our photos, but we don't know and didn't see him. That was really out of sight! I didn't know what to think. May be it was ghost or UFO. I felt solicitude for this problem for a whole week. And I was very worried. And looking to my worrying my friends decided to confess. As it found out, it wasn't a ghost; it was simpler than I thought. It was Photoshop. My best friends decided to make a joke about me. I was so angry on them. The whole week I scratched head over these photos and they laughed at me. But I can't be angry for a long time on my friends. But now I puzzle my head how to play a joke on them.
