I didn't go to work today!

Okay so today i got up at 0500 and got ready for work i put on a skirt and a nice shirt and i went to work. When i got to work one of my co-workers asked me "are you suppose to be here today?" i was shocked that she asked me and i said "Yes because i took thursday off and i thought that i would at least come in at the begining of the week." they told me that we were going to be working 30 hour weeks for a couple of weeks. So i went to home and went back to bed.
