] wasn't it brave though of old Jolyon to take the first step back to his son. And to tell him so honoustly that he was feeling lonely.

I like Old Jolyon very much, too, and I am somehow proud of him for being so forgiving and obliging.
But on the other hand I can't help wondering if he would have tried to get in touch with Young Jolyon and his grandchildren, too, if June had not left him. Now June is so busy with her fiancé and wedding, he has naturally become lonely. It is very understandable that he now turns to his son.
But, since I like him so much, I would like to believe that he would have forgiven his son, anyway, and not only because he is in need of him now. This seems rather selfish to me, along the lines of "Now that I am alone again I might take the trouble to look for some other company, my son whom I didn't care a straw for during the last years, might do for it"
IIRC there is no mention of contact to his son before, apart from the money he offers.
So do you think he has really missed his son all the time or is it really so that he only began to miss his son when June left him?
Any opinions?
