I have found that I can be in a room full of people, and feel absolutely isolated and lonely. Perhaps this happens to you, too.
So, there is something more going on with loneliness than just needing to be around other humans.
Perhaps we are lonely for this, that, and the other.
When I take care of a garden, I feel that the flowers, vegetables, herbs, and all that grows out of the soil are my friends. So, I like visiting the Hartford Flower Show, the Bronx Gardens, and the Durham County Fair.
