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.
One 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 is here: TIFU by taking the wrong class for 2 weeks and only realizing it today
Explanation: 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: Text: so this actually happened today, unlike most of the things on here. so one of the things i do for fun and to make money is teach tennis. there's a friend/coach of mine who i help out giving lessons 8-11 am once a week. so after exchanging some confirmation texts last night i go to bed around 12:30. that's the first fuck up. so stupid me, since my parents are out of town, decides that setting four wake-up alarms 10 minutes apart starting at 7 am will be sufficient to wake me up. usually alarms don't work very well for me because i have mild sleep apnea which makes me a really heavy sleeper. or maybe it's just because i'm a teenager (for a little while longer anyways). usually my parents wake me up. anyways, long story short, i wake up at 10:50 when a plane goes over and rattles all the windows. so now it looks like i blew off my friend/employer/mentor, and i missed making $60. i feel like an asshole.
Solution:
TIFU by not waking up.
