My italian friend

A few months ago I met an Italian guy in a concert, he just came from Italy, where there is no jobs, he was lucky because he already had a job before even come to UK. He didnt speak anything else than yes or no, really anything else; he didnt have anywhere to stay so I let him stay at mines, I have no problem, I had a spare room with a bed in it and the guy was looking cool, after 3 weeks (yes a bit longer than I thought) he moved to another city even though he was coming to visit me every weekend, I thought his english was going to get better now that he was living with english people but not at all, in his free time he was on facebook for hours or just watching italian movies. After a few months in his cooking job in an italian restaurant, he tells me that he quits his job because he can't stand his boss, I just asked him if he had anything in mind to work after the drop but he didn´t. He asked me if he could stay at ay place for a month or so until he found a new place, but when I asked him to pay the rent 50% he said no quite upset. He is a good guy and I won't keep a bad memory at all but there are people who even they are old enough to get drunk, take drugs, drive or vote are not responsible for their lives at all.
