You're so BLIND!

I was doing add maths questions on log. I copied the question and did it on another piece of paper. I was doing and doing, and then after quite some time I can't find the answer. I know how to do it. It should be this way. But I can't get it. I was like 'Kenapa??? Kenapa tak dapat??? Bukan macam ni ke caranya??'' I was so fed up I can't get the answer. So I looked back at the question and realized I copied the wrong question. It was a positive symbol and I copied negative. OMGOSH I FEEL SO WHAT THEEEEEE HELLLLLLLLLLLLL! I SCREAMED!!! ARGH!!! I WAS TAKING SO LONG WTF THIS QUESTION ASYIK TAK DAPAT JE. IT WAS ME! SO BLIND! -.- AND THEN WHAT I DID WAS TOTALLY RIGHT. IT WAS THE QUESTION!!! ZZZZZZZZZ... Sometimes this things can make me STRESS!!!
