Things I have learned over the past few days : 1 . Green tea can not be kept until the afternoon because bubbles will form and it will have the weirdest taste after that . ( But asking people to drink it and watching their faces is always fun wtf ) 2 . Haagen Dazs has ice - cream mooncakes !

Question: Why ca n't green tea be kept ?
Because it wo n't be appealing to the palate .
