I saw a woman at a store. She was shopping, just like I was, but she was happily singing along with the classic rock music coming across the PA system. She would stop to greet people from time to time in a cheerful voice, carry on a conversation, and then return to her singing.
She seemed perfectly happy and comfortable in her own skin.
I found myself a bit wistful as I watched her, wondering what it would be like to be that unselfconscious.
