Misery Loves Company
(unhappy people often get satisfaction from having others share their misery)
Hey Misha, what's wrong?
Oh, I just had a run-in with my math teacher over the grading of my last exam. Although I got a wrong answer on one of the problems, I did use a correct equation and he refused to give me even partial credit.
Don't feel so blue. You're not alone. I'm kind of in the same boat myself, only with my history teacher. I got a really low grade because she didn't like my essay.
Although misery loves company, I don't feel any better knowing that you're in the same predicament.
At least I tried. I thought you might get some comfort from knowing that someone else shared your misery.
run-in = 口論
predicament = 苦境
