It's been a long time since I left hostel but I still remember all weird character I met during my hostel time. Sharing room neither easy nor it is taught in any book. However, it can only be learned by experience. I learned it through terrible experiences with my room partner.
Some roommates will be crazy; some will be serious and unbearable although at some point in time we have to bear them. I bet that you must have some funny and horrible experience while sharing your room. I have some funny but honest confessions about horrible roommates, let's have a look.
