You may be right, but I think mostly, of all of us, Simon is the most interested in doing good -- he is mostly very worried about his sister.
It can be, but it doesn't have to be, and at home it certainly did not happen overnight. Talk to him, see how it goes, and if you ever need a cup of tea, my door is open to you. I'm less good at the going out to a bar and beating someone up way of de-stressing, but tea I'm very good at!
