Food psychologist Dr Christy Fergusson believes people view cakes as an innocent treat to be shared.

　　食物心理学家Christy Fergusson表示，人们将蛋糕认为是一种单纯的分享。

　　She added: 'It's quite worrying that we're so suspicious and paranoid. 'Maybe if we all treated our partners more often we'd be more likely to accept the sentiment rather than start worrying. '

　　她说：“猜忌和怀疑对谁来说都是件苦恼的事情，可能只有当我们频繁的送出礼物，好让对方接受这种的感觉，而不是担心。”
