Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Text: title speaks for itself really... 
i just wasted $1500 of my parents' money.
i feel terrible.

edit: i guess it wasn't that i took the wrong class, but the class i was taking wouldn't transfer credits over to my university. so really it was my negligence to do more research in the matter. gg
Solution: TIFU by taking the wrong class for 2 weeks and only realizing it today
Reason: This title is appropriate for the given text post because the focus of this post is about a humorous situation caused by "taking the wrong class".

Now, solve this instance: Text: my buddy, his girlfriend and i have all been really good friends for a couple years now, but a month ago she broke up with him pretty much because she wanted to go and sleep around. but when they split she turned to me for support.

 one thing led to another and only a week or so after they broke up, me and her were sleeping together. i fucked up by getting feelings for my buddies ex when i fully knew going into it that she wanted to sleep with other guys.
Student:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
