I happened upon this song recently. Somebody That I Used To Know by Gotye. If you know then you will understand why this song is so impactful. There has been much on my mind of late. I have talked with certain confidantes and made promises to let these thoughts go. For as much as this song reminds me of what was, it also informs me that all things - people, friendships, relationships - eventually pass away and are relegated to once upon a time.
