Input: Text: so like most tifus, this happened not today, but several weeks ago. this is so pathetic it might not even be considered a freshmen move (in college). i woke up an hour early on the day of my chemistry final and to my horror, could not find my calculator. following the advice of my brother whom i called, i decided to go full retard and just pray to god someone else had a calculator. when i arrived, i quickly began asking everyone for one. by the time i reached the front row i prayed to freaking jesus that my professor had an extra, but even jesus had to let me down...but when all seemed lost a random girl said she had an extra and i was thinking "sweet jesus". first problem on the final, the calculator gave out an answer in fractional form and i was like holy fuck because it was one of those "what is the mole fraction from part a" kind of exams. somehow managed to click random shit and i got decimals ftw.
