I finally went mad

I can't believe it, but this morning I thought was Monday. I didn't get much sleep last night so getting up at 6:30 am came very hard for me I kept hitting the snooze button until 7am, dragging myself out of the bed got dressed before going downstairs because I knew I didn't allow myself enough time like I usually do to wake up and get ready for work. So after taking care of the dog needs and getting my face on, I went upstairs to say good bye to Peter, as he was half asleep he didn't notice I had my uniform on leaving for work, with a sleepy Have a good day I went off to work. As I was driving I did notice that there wasn't as many cars on the road for a usual Monday morning passing the gas station which was closed I happen to think it must be a bank Holiday and everyone is off work. Parked my car and got out with my big mug of coffee, I walked into the doors at work.... Went into the kitchen and a different person was on duty. She looked surprised and ask was I working today, and I said yes and ask her was she working for the girl that normally works on Monday... Then she says the dreaded words... This is Sunday.... I could not believe it. I said you have to be kidding... Then it happen to dawn on me the less than normal traffic on the road,gas station closed and different people working that I normally work with on a Monday.... What a nut case... To add insult to injury it turns out that it is April fools day.
