his brother. He has done it twice, first time I thought he would not do it again. But he has. It's when his brother has annoyed him, last time when he was playing and then this time when he took one of his crisps. It's left a mark, second time was worse. Not really sure how to play it. Any ideas? I feel like he's got a bit more aggressive in general, it probably is an age thing too? 3/4 seemed to come up a bit in Google
