"Well, Harry's got a wonky sort of cross -- that's trials and suffering. But this here could be the sun -- that's happiness. So... you're going to suffer but you're going to be happy about it."

 * In third year, during one of the Divination lessons, Professor Trelawney read the tea leaves in Harry Potter's cup and saw four things: the falcon, a deadly enemy; The club, an attack; The skull, danger in your path and the Grim, a spectral dog which is an omen of death.
 * In the same year, during the same Divination lesson Trelawney read the tea leaves in Neville Longbottom's cup and commented that it was not good. After she asked if his grandmother was well.
