before programming class:
"yes easy af, imma finish this in a few minutes"

during programming class:
*types everything in 10 mins*
*compiles and runs perfectly*
"wtf this isnt supposed to happen"
*spends 30 minutes trying to find the bug*
"fucking hell, it should fucking work by now"

end of programming class:
"oh i put int instead of float, good job, my time was wasted because of one fucking word"
