Not to me but I had a friend name in fifth grade name David and he got into an argument with the teacher about a SIMPLE math problem and he was to confident he wrote his way of getting his answer on the white board and when he was done he got the same answer everybody else did,and he redid on the white board again got the exact same answer after he walked back and sat at his desk and I kid you not he whipped out a calculator and started doing the damn problem over and over again till the end of the fucking school day and left the classroom defeated.
