Lack of Hours

Don't take this as me just bitching and complaining. I mean I know that it kind of is, but I have my reasons.
I told my boss to work me this weekend. That my family was going out of town and when I'm not working I'll just be sitting around the house doing nothing. She told me she would most def get me the hours. I went in today to check my schedule and I have 15 hours is all. :( Normally, I would be very happy with that just not this weekend. I am able to pick up up to 3 more hours on Monday. It's supposed to be slow though and she already warned me she'll probably send me home early.
If I had more money, I'd be pretty happy with this. I'd just spend the time off going to movies and maybe driving down to Devils Den to hike. I may still go to the movies once and will just have to live with Tanyard Creek Trail. There's a way to compromise. A way to figure out how to still get what you want and be happy. I'm learning how to be like that. I'm trying to see the positive in stuff more. Right now, I still think of the bad first but a little later the good does come to me. :)
