Shopping habits

I live in the US since five months and –of course- not just my eating habits (yes, I do eat a lot of junk food and yes I gained a lot of weight) also my shopping habits are getting more and more American.
Maybe it is because I have more money than I ever had, since I am far away from my parents and I use their money and I don`t know exactly why, maybe they kind or forgot that I am a horrible daughter or something, but what I wanted to say is, that they are a lot nicer to me than normally (money wise).
And I am a girl and everything is cheaper here, so it`s even a little bit good, if I buy cloths here and not in Germany. I think, I have to mention, that I arrived in the summer with just one suitcase, with just 40 pounds, which is nearly nothing. It was okay for me, I went on camping trips before with far less than that. But the US is no camping trip and it is common sense here, that you have to have a full closed if you want to be accepted. Of course in the beginning, it is not too important, but after a few weeks you should have about 20 t-shirts, 4 jeans, 4 sweaters, etc.
I never cared too much about shopping (probably because my mum never liked it) but I have to say, it is a nice feeling to do it. I am compared to most other people a good shopper, I look at the price, I don´t shop irrational and from time to time I feel bad for all the little kids in China, who made my clothing.
But one thing is sure, I will fly back with just one suitcase, but I will send at least five big packets.
