Living alone has its goodsides because you have more time for yourself. Nobody can distract yor mind from learning.
But, on the other hand, living with somebody has its good sides, too. For example, if you are busy and you can not do your shopping, pay your bills, or cook your lunch, your roommate can do it for you. Also, if you are living with someone, you will never be bored. But it doesn’t mean that you should spend all of your time socializing. You two should have an agreement about studying time, socializing time and also a list of ‘to do stuff’. Otherwise you will argue easily.
