Input: Text: really, this is a series of fuckups on my part. for one, i neglected my teeth enough that i had a small cavity that needed to be filled. in addition, i woke up late and didn't have time to eat before my class (i'm a student), and my appointment to have my cavity filled was 10 minutes after my class ended, so i didn't have time to eat right before the appointment (plus, i would feel bad for having a dirty mouth for the dentist). now, i guess i should have expected that they wouldn't let me eat after the filling. they said to wait till the numbing was gone. now it's been about 2 hours, and it hasn't worn off. i have to go to work (at a restaurant no less) in a few more hours, i'm just hoping my fuckups mean i don't go hungry in a building full of food.

TIFU by not eating before going to the dentist.
