Well, maybe Wayne is not perfect and sometimes was rude with his fiancée and this is not good at all,
but with Chris he was like an angel, I mean was not an obligation for him to host Chris, to give him a job, a safe place to stay, a chance to take a rest for a while earning money etc...but he was so courteous to do it...he understood Chris better than his family did, so I can definetely put myself in Chris shoes, and does not seem strange to me, at all, that he did not want judge Wayne and so 'addressing the issue' as someone wrote.Maybe
Chris thought something like this:"Who am I to blame a person who did and does so much for me, without having any advantage, only for his natural attitude in helping others?"...Wayne is a human, is not perfect but even if with some faulties, he is a great man under other aspects (Chris said and wrote so many times). Chris admired Wayne, was grateful for all the help he gave to him, for the happy moments spent together, the job, the money, the sincere friendship that last even now, even if they were not long term friends he was available to talk about their frienship, to meet the family, and many other things...thus Wayne is a nice person, he must be a good one, it is quite clear to almost everybody, I am sure about it, for this Chris felt so close to him and enjoyed his companionship.
Maybe Wayne was not nice with Gail that night or perhaps in more other occasions, I hope no! And as a woman I am truly sorry for Gail, as of course Carine was, so I partially understand Carine's feelings, but considering what Wayne did for Chris, I am not sure he is a bad man, violent and rude...maybe the night that Carine wrote about in her book, he was drunk, and particularly emotional for the situation is not a good reason for bullying some one, but why we have always to see the bad things? Wayne makes mistakes like everybody does, and anyway we are all here for Chris not for blaming who gave him probably the biggest present ever: a bit of happiness before to pass away...think about it.
