Hippies, burn them all[

No, seriously. Until recent I lived in a house with 3 others, 2 of them students, 1 of them a junkie in rehab. Apparently, some people lack every form of self control. One would suspect that there's a certain degree of social skill in every one of us, but that's simply not true.
Living with other people is always difficult if you're in a different (bio)rythm. Among students, this comes forth quite clear. For 'civilians', you'd expect that people try to go to bed approximately on the same time. In your case, you should point out to your inmate what he'd do if he'd live next to the railroad track.
Hell, he shouldn't even complain: if he isn't bothered with sounds from outside the house, he's statistically one in thousand, so he's pretty lucky... Buy him ear plugs.
