I'm worried about my brother. He eats a lot of junk food. He's already eaten four doughnuts and two packets of crisps toda and it's only 11 a.m. And he's drunk three cans of energy drink. Last night, he told ou mum he wasn't hungry, but he went to the shop and bought chocolate. He's always in a bad mood. I tried to talk to him about it, but he got angry with me. In fact, he hasn't spoken to me at all this week. My parents haven't noticed yet. Should I say something to them? Damon
