Everything was my fault!

Have you ever had one of those days when everything was your fault although you had nothing to do with it? Something like that happened to me recently. I was the one that was blamed that nobody at the college I go to could cite correctly! Students in their research-papers or diplomas, professors in their MAs and PhDs - nobody could do it! And apparently it was all my fault - at least it was according to the person that spent 20 minutes shouting at me about that! And all that because I made a tiny unimportant mistake when citing the title of 1 book!
You wouldn't believe the things that can happen to you if you catch a person on a bad day!
