It's not been my day.
재수가 없는 날이에요.

John: How could someone possibly get a hold of your credit card number?
May: Beats me. I have no clue. But look how much they spent with my card!
John: Thank god， you only have to pay for the stuff that you bought.
May: I know. It's just such reckless spending.
John: My god， I can't believe this person spent $59.60 on shoeshine materials!
ay: That's me.
John: Oh， sorry.
May: See， I feel just miserable today. I was laughed at at the company because I left my notebook open after the meeting. People were reading out loud what I said about Mr. Cradle. And now I got this huge bill that someone made with my credit card! I'm…such a scatterbrain， such an idiot!
John: No， no， no， May. You're kind of losing it here. It just really has not been your day. That's all. You know， everybody has a bad day.
May: I wish it was one of those days， but something tells me I will have to go over this thing for weeks!
