Living with someone can have a lot of advantages but also and disadvantages.Some people claim that living alone is better because you are not alone. While others prefer to have their own freedom.
The main advantage is that you can plan your time and use your space as you want so that you can live more peacefully, organised and independent life. Also, living with someone can prepare you for stressful situations at work, school, socialising etc,..Another advantage is that you do not have to pay for bills on your own.
On the other hand, sharing space with a slob can be very annoying especially if you are neat person who likes to maintain an order. Secondly, not knowing person who you live with can cause unpleasant suprises.
In conclusion, it all depends on your personality and compatibility of you and a person you plan to live with. It is better if you live with your close friend than a comlete stranger.
