I was at a party with my friend and all he had to drink was one shot of liquor and a beer, but he doesn't remember anything from the night. The last thing he remembers was finding some glowing spray paint (it was a black light party). He sprayed it on the walls and then accidentally got some around his eyes and face. He didn't act drunk at all but he was really angry (punching walls and throwing drinks at people). Could that have possibly caused the memory loss?
