westerhof was loling at JJ aces at times and jerzy once ranted to the umpire for no reason (well, he had a reason, but he was a break up, outplaying the opponent, he should learn to really ignore some mistakes because it usually costs him on the mental side)
Why was Westerhoff laughing at Jerzy's aces? What is so funny about that?
Jerzy was mad because he was winning?
Maybe he wants to always be two breaks up instead of one. Maybe one break isn't enough to make him feel like he is in control?
