Here you will be expected to live with a complete stranger in perfect harmony. Although the thought of having someone unknown living with you for a year sounds a little unappealing you can be the sure the experience will help you deal with people for the rest of your life. Who knows you may become bitter enemies, but on the other hand you and your roommate could become best friends, or at least friends. To make the school year as easy as possible I suggest taking the friendship route. If your roommate bothers you at first then you must tell them.
Communication is the key to living together peacefully.
You may be in the same classes and can even study together at times. Another issue that needs to be discussed is trust. Of course you cannot do this unless you have security cameras in your room. So for the sake if getting along you must trust you roommate and realize they trust you just as much. Eventually you will begin sharing things and you won t mind lending things out, or borrowing their stuff too.
