To cheer up is a phrasal verb which means to make someone feel happy.
The other day a friend tried to cheer me up by sending me this picture. He said in his email that when he saw this it reminded him of me. And I thought, ok I might not be a technological genius, but seriously, I’m not delusional. I know I don’t have an i-pad and it’s very rare that I run out of wine, so now I’m wondering, was he trying to call me a moron? Furthermore, considering I’ve known him for over 20 years, he knows that all he needs to do to cheer me up is to post me a divorced George Clooney in a flatpack! I’m just that simple!
