I heard a little bit of this programme. I am very sceptical of the term friends. I used to think that it was possible and necessary in this world. Now I can see that one has fellow travelers and not friends. I think I am now cinical. Or may be I expected of friendship more than it is. It probably still exists in our time, but one should not count on finding it.
I'm sure it does still exist t-p. I have a few true friends - and many acquaintances! Don't get too cynical: surely it's better to trust people and be conned once in a while than never to trust anyone.
When I was growing up, my Mum, an English teacher, used to advise me a lot via Shakespeare - a great love of hers.
From Hamlet: "This above all, to thine own self be true..."
and, on friendship: "the friends thou hast, and their adoption tried - grapple them to thy soul with hoops of steel". The important words here are "and their adoption tried".
As always, Shakespeare, the great psychologist, hits the nail on the head.
If you have any problem understanding the language of Shakespeare in this casde - though your English is very good and seems to improve daily - please ask. I'm sure any of us will be happy to explain further...
