Input: Text: so, unlike most other submissions in this subreddit, this actually happened today.

so, let me give a small backstory, i am a high school senior, and so is this girl (just for privacy's sake, let's name her "mary"), who is easily one of the most attractive people in the school. we both have advanced placement computer science class at the end of the day. i tend to keep to myself most of the time, unless someone needs help with writing one of the programs we're working on (java, ugh). in that case, either i go to them or they come over to me.

so, i was just sitting there, listening to music, when out of the corner of my eye, i see mary headed in my direction. not sure if she was headed to me, i casually took off my headphones, looked in her direction and gave a slight smile. she pulled up a chair next to me and immediately began asking questions about the assignment we were working on. after helping her out, she asked if i was going to homecoming. she wasn't the first person to ask this question, so i just recited what i told the previous 4 or 5 people, which was "probably not, i'm not really into dances that much." she followed up with "well, do you want to go?". here is my fuck-up: i barely got any sleep the night before, so i was well beyond tired and didn't realize the significance of that question, so i responded with "no, not really. i mean, i haven't gone for the past three years." she then got a really confused look on her face, then just said "oh, okay", stood up, then returned to her desk area.

i didn't really think much of it, until i got home, then it hit me. now, i feel like shit and have no idea how to recover from this.

TIFU by being tired and rejecting a girl's invitation to Homecoming
