Not to happy at 6:45 am

So at 6:45 this morning I was getting ready to leave for work since I had to be there at 7:15. All was quiet in the house until my home phone rang and woke up Matt and my dog.. So now this is where I am mad I answer the phone and its my boss she is telling me never mind you don't have to be in until 7:45 (our normal time)! WTF Hello its now 6:55 you could have called a little earlier and I would have been able to get more sleep!!! And this my friends is the start to a very long day/week....
