Alex has seen Tom after 16 years and he was very surprised and happy to met him.
First Alex and Tom talked about Alexs holidays in Australia and suddenly Alex asked Tom why he left Alison and him and why he never sended a birthday or christmas card. Tom was very surpriesed about this directly question but he wanted to explain his reasons why he didn't call him anytime or send Alex and his mother a letter.
Alex first didn't understand this reasons but a few time later he know, that he can't be sulky with Tom all the time and so he has try to understand them.
