Input: 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.

TIFU by not waking up.
