I love this Dennett! I never thought of facebook like that but you are right. I feel so much lighter now that I have given it up. I got so caught up on the past relationships that I thought they were still current ones. But they weren't they were in the past. It's interesting how I left facebook and joined Medium all at once. I left the past and found the future! So cool! Thank you for this eye opening piece. I know what you mean about friendships as well. Sometimes they are more of a convenience than anything else.
