It often takes many more than one visit to persuade a rough sleeper to accept help. The idea that a charity can simply sends its staff to offer sleepers alternative and positive options. and, bingo, the problem is solved is naive in the extreme. Yes, some people are on the streets because of rent arrears, unemployment, wife/husband/parents/friends chucking them out and they will jump at a chance to get a roof over their head and get back into normal life, but as I said before many homeless people are mentally ill or have deep psychological problems or because of these problems have addictions and they have behavioural and other challenging behaviours that make helping them and getting them off the streets very slow and difficult process.
