alright, the foundation for this fuck up actually took over a couple weeks. i've traveled recently, and i almost never remember to pack a toothbrush, which has led to me owning two toothbrushes outside of my primary toothbrush. one toothbrush, i got a couple weeks back, is the one behind the fuck up, and another toothbrush, one i got last week, is the reason why i used the fuck up toothbrush. 

as  i was getting ready saturday morning, i was ready to replace my primary toothbrush with the toothbrush i had gotten last week, but i couldn't find it, so i settled for the one that i had gotten a couple weeks before, and this is where i fucked up. i went downstairs, and proceeded to brush my teeth, very thoroughly, with the toothbrush from a couple weeks ago, and it wasn't until i was done that i realized i had fucked up, and just spent the last five minutes brushing my teeth with the same toothbrush i had used to clean my sneakers about two weeks ago. in my laziness, i forgot that i had used it to clean sneakers, and put that same toothbrush in  my mouth, and on my tongue. i found the toothbrush i had been looking for, and proceeded to brush my teeth again, for about 10 minutes, with a shitload of toothpaste. now, i've made sure that the sneaker cleaning toothbrush is where it belongs so i don't repeat this fuck up again. i still feel like i need a new mouth.
