1. The snow most likely symbolizes peace.
2. The theme symbolized by this expression is that of Reconciliation.
Step-by-step explanation:
The description of the disagreement between the couple in this story showed a heated atmosphere prior to the onset of the snow. When the snow began to fall, peace returned between the couple. They were then able to talk about their misunderstanding and peacefully resolve them.
The theme symbolized by this expression is that of Reconciliation. Reconciliation is the act of resolving disputes. Initially this was not possible, but the onset of the snow made it feasible.
