Am I supposed to?

My job was on lay off for a week and I was having a ball while I was off. I did some cleaning but mostly I had fun visiting friends and family.
I work weekends and was excited to have two weekends off. When ever we have a shut down we don't go back to work until Thursday. No matter how many weeks we are off it is always Thursday when we go back. Period. Never before that.
On Friday I went with my bff on her delivery route. We spent the day driving all around NE Missouri and SE Iowa and a little bit of Illinois. While in Illinois we stopped in Nauvoo and made plans to go back with some other friends in a couple weeks! Nauvoo is the town that the Mormons were kicked out of in 1846 during the winter and they had to cross the frozen Mississippi river on their way to Utah. I am really looking forward to learning more about what happened back then. My bff and I decided to go to the movies and see "He's Just Not That Into You" sometime this weekend.
Then on Saturday I went to breakfast at the historic school house in my little town. Afterwards I went to the "dog sale" which now is mostly a flea market. I was looking for baby Muskogee ducks for my DIL. She likes them for pets and only wants two or three but to order them you have to buy twenty. That can be very costly besides she doesn't want that many of them. I was out of luck. It is too early to have ducks and chicks there yet. Too cold. On the way home there was almost an accident between a truck and a train but I will post about that later. On the way home I was thinking so hard about the truck/train thing that I ended up turning right instead of left and ended up in a whole different town ten miles in the wrong direction. The reason I didn't realize sooner that I was going in the wrong direction is because I was in an area I don't usually drive in and it is all country side with maybe five homes along the road. After I finally got home I did a lot of cleaning. When it was too late to go to the movie I remembered that we were going to go. I called my bff and she had forgotten too so we decided to go on Sunday.
Sunday, I got up early and started doing more cleaning. Did some stuff outside and came back in. Then I got a phone call. It was my boss. I was feeling really good and was very bubbly and he was too. I was wondering, why is my boss calling me on my day off? Then he asked me if I was going to come in to work today? He said he looked but I hadn't asked for a vacation day for Sunday. While he's saying that I'm saying "Oh, my God! Am I supposed to?" He laughed and said that we are scheduled to come back on Sunday. He said some of the girls told him that I must have forgotten! He was very nice about it and told me not to hurry so much that I get into an accident. He was having a rough start up and the reason he didn't know that I wasn't there for an hour and a half was because only one of three lines were running so no one was complaining to him. I got there and everyone was teasing me but all was fine. It was silly because we only worked that day and now our shift is off until Thursday but the other shift is working.
