SUBREDDIT: r/tifu
TITLE: TIFU by looking up my third grade teachers dress (skirt?)
POST: This happened when I was in the 3rd grade (I'm a Junior now). But I literally just remembered this shit so, time to tell you this wild ass tale. 
So we were all sitting on the floor by the front of class. Everyone was fixed on the book (shocking) and looking at the teacher at all times, me being easily distracted, I got bored super easily. I immediately put eyes on her dress and my third grade mind decides to shoot up with thoughts. For starters, and the main thought that made this possible, was "what was inside her dress?" So I, again a third grade boy, decides to find out. I go in and I look up, and I fucking see vag or god knows what. I immediately got my head out, face burning red, and moved to the way back row. To make things saucier, not a signal kid, not even the FUCKING TEACHER, noticed that. Either she just ignored it and ended up forgetting it, or is that focused on the book. Thinking about it now, I now want to bleach my eyeballs and remind myself to tell my kids to not do what I did.. 

She wasn't old. About, I would say, 33 at the time.
TL;DR: 
got bored/curious AF. Looked up teachers dress. Saw vag or whatever was up there. No one fucking notices. Regret ever remembering it.
