I don't think it's that we don't care but we don't know how to respond. People train a long time to learn how to handle these sort of conversations, it's not an easy thing to do.It is difficult for men especially to find the words . How many times we say how's it going mate, you ok? And we expect one answer back , yeah not bad .. I asked my boss the other day , and when I said you alright,? , he said no . It was the first time in 30 odd years and the 20,000 time I have said the words you alright and somebody said no , it completely threw me , I wasn't prepared for that conversation to to go any further . In the end I tried talking to him as I know he's having marital problems , but he shut it down and said it was private . I have tried a few more times and he doesn't want to talk , but my point is, we ask the question are you alright , but for how many of us do we really care? Or is it just something to say , maybe we should actually mean it when we ask , because I know I do for people now
Family and friends are often not the best people to deal with these situations. With the best will in the world they will often say the wrong thing or the thing they think the 'sufferer' wants to hear.
