My most recent argument

A few days ago my mother and I got in an argument about money. I am going to Robert Morris in Chicago next year and cost to go to school and live down there is a bit on the expensive side. My parents think that it is fair to help out and start saving money so I can help with the expenses. I agree in with that, but I am a teenage girl that likes to shop. I work in the juniors department at Carson's. I get paid decent there, but I like to spend my paycheck before I even get it. I buy clothes all the time. When I am at work I am always picking out my next thing to buy. My mom has been telling me to stop buying stuff I don't really need. Sometimes she doesn't care and other times we get in huge arguments. I understand that I need to be saving money, but I also think its my money and I can do what I want with it. Yesterday there was a sale on the coach and dooney and burke purses, which never happens and so I bought something and when my mom saw I bought it she flipped out. My argument is that I will start saving but those purses are never on sale. Since I work there now I should take advantage of it. My mom didn't agree and yelled at me. She says that I don't get how important it is to save money. I know that I have to save money, but I just think things like college will be paid eventually. I am not the only one that has to pay for college. I am alot more well off than a lot of people. In the end I agree with her and i will start saving. Saving money isnt something i like to do though.
