What is the concept of friendship portrayed in both Society and Solitude and Chapter 1 of Nature

Friendship is considered to be valuable but not necessarily vital.

In "Society and Solitude" Ralph Waldo Emerson portrays how he feels that the independence can strengthen friendships. On the other hand, In "Nature" Emerson shows that the friend are trivial, that even when between the people exist close bounds each person is ultimately alone, in both text he considers the friendship trivial.
