Before read the 6th chapter

"Predict what Alex tells Tom when he meets for the first time after 16 years??"

I think that Alex ask his father why he had left his mother. I can imagine that they speak very serious to each other because they meet the first time after 16 years! I think too, that they get to know more about their lifes. They still like each ohter, I think.
What do you think??? Do you agree?
