Today I was at DG Zone X when I saw this girl playing the dance
machine. I saw that she scored the highest with a superb
score.
So I couldnt resist playing the machine as well. But I didnt expect
to beat her score by more than 50000 points and I overtook her
position and became the top scorer for that machine of the
day.
When I look backwards I saw that she was staring me...her face
slightly black black...
Den later I walk away, I saw her playing the machine again and she
was playing in a very competitive manner....clearly, she was
unhappy. 
Now I feel bad....
What should I do?
