When I was 14, it was discovered that one of the handsomest boys in school was the "boyfriend" of the parish priest in our local Catholic church. The guy was 17 and came from a poor family; he had started singing in the church choir at 13 and, about a year later, the parish priest visited his parents to suggest a mutually convenient arrangement: he would pay them quite a lot of money every month, as long as they would prostitute their son to him. They obviously agreed, and were instantly lifted from poverty.
I never knew how it all was revealed (adults refused to mention it around us children), but everyone spoke about it and it was a HUGE scandal in the area. However, as this was the mid-90s, the parish priest was simply transferred to another church and the boy's family moved elsewhere - this happened in the old town of a very large city, and in the quarter where I lived everyone knew each other, but it's very likely that people in other areas would have never even heard about it.
Also, the mother of one of my classmates died of an aneurysm while sleeping. This lady was a teacher in our school and was EXTREMELY popular with the rest of the faculty - the sort of person everyone looks up to, for God knows what reason (she wasn't anything special by any stretch of the imagination).
Because of this teacher's popularity, her very mediocre and insufferably arrogant daughter was treated like royalty, and everyone kept singing her praises even though she was an average student at best, was plain as dirt and had the personality of a famished piranha.
Well, one day the mother didn't wake up at the usual time and, when my classmate's brother went to wake her up, he found her dead. Yes, it was a tragic situation, but you would have thought that a national hero had died by the way in which everyone at school reacted. Many people were behaving like the world had ended, and I regret to say that I didn't care, even though I never dared to show it (I perfectly understand the feeling, R7). There was a huge funeral and everyone attended, and then my classmate and her brother went to live with their wealthy grandparents, and were never heard from again.
The thing that shocked me the most is that people who claimed to be heartbroken and made ridiculous displays of grief, had forgotten all about it a week later, and were behaving as if nothing had happened. Also, many classmates who swore to the deceased teacher's daughter that they'd be best friends forever and loudly wept with her, started bitching about her just a few days after the funeral, and never even tried to contact her again. It was downright spine-chilling, how everyone claimed to be deeply affected by what had happened and a few days later, it was evident that they didn't give a damn.
People are strange and will do anything for money, or to project the right image in front of others - those are the lessons I learned from these experiences.
