while arriving to a music venue before one of my band's gigs, i noticed my car was overheating. being an irresponsible person that already had a few drinks on the way to the show (first fuck up), i decided i would open the radiator cap before allowing the car to completely cool off (second fuck up). i understood the dangers involved but decided i would be fine if i used a rag and slowly let the steam out before removing the cap. i had it under control for a minute before the cap shot out of my hand and coolant sprayed me in the face and soaked the right arm of my sweatshirt. i quickly washed my face off with puddle water and then realized my sweatshirt was stuck to my right arm, burning it badly. i removed my sweatshirt and rinsed my right arm off but it was too late. i would find out shortly after that about 60% of my right arm suffered 2nd degree burns. 

in a ridiculous amount of pain, i ran to a cvs down the street to purchase some burn cream, gauze, tape and whatever first aid products i thought i would need. this is when i learned that there are like 1000 different types of burn cream, all with specific applications. i was in too much pain to focus and grabbed supplies as quickly as i could. 

when i got to the cash register, the employee initiated small talk, asking how i was. i throw the cream on the counter and exclaim "worst burn of my life". keep in mind, at this point, there were no signs of a burn other than the look of pain on my face. my arm wasn't showing any indication of a burn yet, other than a little redness that was hidden by my tattoos.

it wasn't until i went outside and gave the supplies to a helping friend that i was informed i purchased hemorrhoid cream while telling the girl at the register that i had the worst burn of my life.
