The weather certainly reflects the mood of what is happening with Gianni. He questions everything he does when I doesn't get the response he expected. Gianni feels the things they have in common should strengthen their relationship, but doesn't see the differences that makes it harder for Sami. Gianni misses his parents, but Sami is so young he probably feels more like he has been abandoned by the adults and fears to get too close to Gianni and Angelo.
Gianni did fit in the community faster, but had the language and background to do that much more quickly than Sami. Gianni talked about accepting his family, but seems to forget the great difficulty he had with his grandparents, especially his grandmother. Gianni is trying, but he needs to be more patient and not overthink the problem.
