Ben, 17, is a member of their school basketball team. He is crazy basketball and pretty good at it but they (lose) their last match. In Ben's opinion, their point guard was (blame). (disappoint) by his behaviour, Ben told this to his best friend. However, his best friend told everyone else he'd said. Ben didn't know what to do, so he asked Agony Aunt for help.
As far as Agony Aunt is concerned, it is (main) his friend's loose lips that make the situation (bad). But it's partly Ben's fault. She suggests that Ben should apologise to his teammate. Secondly, Ben should tell his friend that he is (anger) with him for repeating what he said and making the situation worse, that he wants to move on. Thirdly, Ben should think about his own behaviour and always remember: think first, speak later. If he feels one of his (teammate) isn't pulling their weight, he will raise his concerns in a professional way with his team coach.
