As happy as a lark,over the moon(形容很开心的感受）
face turn crimson,seeing red(生气）
hit the sack(睡觉）
John was as happy as a lark/over the moon because he done a good deed.
Mei Ling was feeling blue as nobody remembered her birthday.
Puan Lim was seeing red as her children lied to her.
Let's hit the sack early tonight so that we can get a good start tomorrow.
