My FAULT???

Something happened today! I had a long shift today which i had a call in shift yesterday afternoon and comfirm with a female RN that i will come this morning to do the shift! And she did written down my name but not in the main roster page but it's noted in the shift allocation page where if there is any replecemnt for the staff, it should be written in there! so, the night shift RN didn't know that and he is a china man! u guys know lar..if china man done sth wrong, he/she will try to challenge to the people and says that he/she is NOT WRONG! Yes! He did call me this morning but it's 6.12am! Which is impossible if i gonna pick up the phone and the bus has gone even if i pick up the phone rite? but actually the reason why i didn't pick up the call was i am listening to my ipod! that's why! then he called to agency to come to do the long shift because he didn't know i am going to do it! This morning he was like so swt why i came in to work! And yet he said that i was very wrong in the first time! I was like stunt at that moment because he keep saying that This is my fault as i didn't pick up the phone call and he has to call to agency to cover the shift! The other nurse was like..u should have to check every page first and confirm if no one is doing? BUT he didn't know that! sigh! HE SAID THAT WAS MY FAULT!!!! i kept quiet for the whole senario! and he kept ask me whether i have got a miss call from here or not? what if i was in the shower that time? shit!!!
It's too late to pissed off now!
I felt guilty as well as he says that it's my fault!
BUT please check properly before u call k?
I WAS LIKE ...CHINA MAN IS LIKE TAT de!!!
