Input: Text: like a lot of you, this mishap didn't actually happen today, rather it happened 7 years ago when i was still in high school. for those of you who don't know what the [mosquito noise](https://www.youtube.com/watch?v=kz5vdpuveum) is, it's a very high pitched frequency sound that you lose the ability to hear once you age and experience natural age-related hearing loss. 

so, being in my grade 10 year of high school and trying to impress my friends, i thought i would test this out in class to see if our anthropology teacher noticed anything if i played this very high pitched noise. the teacher was about 60 years old and having tested the noise on my parents i was very convinced that she wouldn't pick up on the sound. and she didn't. i kept playing it, and the whole class was starring at me half confused, half in awe. the story should've ended here, but being the high-school teenager that loved the attention at the time, i decided to go full-class clown and follow the teacher behind her with my phone right next to her ear as i increased the loudness to the maximum volume. i followed her around for a couple seconds successfully, but here's where the fuck up occurred. i accidentally waved my phone next to her ear at one point, and i forgot that my phone back then shuffled songs whenever you made that motion. cue a guns n roses song (mr. brownstone) right next to the poor teacher's ear in maximum volume. after nearly giving her a heart attack and probably destroying whatever was left of her ear-hearing capabilities, i received the news that i would be in lunch detention for the rest of the week.
