Lonely, but not Lonesome

The TV program I am watching, Cold Case Files, just had a line that struck me. A girl said that she was often, “lonesome, but never lonely.”

And so I looked the words up on Dictinary.com, and found the following:

lone·some ( (l n s m)adj.
1. Dejected because of a lack of companionship. Producing such dejection: a lonesome hour at the bar.
2. Deserted; unfrequented: a lonesome valley.
3. Solitary; lone: a lonesome pine.

lone·ly (l n l )adj. lone·li·er, lone·li·est
1. Without companions; lone. Characterized by aloneness; solitary.
2. Unfrequented by people; desolate: a lonely crossroads.

And so, I must respectfully, differ from the woman in the show. As for my heart, and me we are lonely, but not lonesome.
