Definition: In this task, you are given a Reddit post as a text. Your task is to generate a title for this text. The title should start with "TIFU by", followed by a situation that caused humor. The title should contain 7-12 words, ideally.
Input: Text: this actually happened nearly a decade ago and i've been lurking on this subreddit for forever so i thought i might as well contribute to it (i apologize in advance for the terrible formatting, as i am using my phone to type this).  

anyway, when i was around 7 years old, my sister had this friend(let's call him xxxxx) who was a senior in high school. her friend had a little sister (let's call her yyy) who i eventually became close friends with. my sister and xxxxx eventually grew apart, but i remained friends with yyy. one day, when i went over to yyy's house, xxxxx was there too. he asked if he could try something on me for one of his classes. of course, i obliged. and then yep. i don't want to go into much detail, but let's just say he did something to me that should have gotten him into jail. from then on, every time i went over to yyy's house, he would do that to me and i had no idea what he was doing, but it hurt a lot. i eventually stopped being friends with yyy, and it wasn't until many years later that i finally figured out that he wasn't "doing something for school." to this day, i haven't shared what had happened to me to anyone, even though it bothers me a lot and i receive constant reminders of what happened since yyy still attends my school.

TIFU by being naive
