When you haven't seen someone in person for so
long that you begin to
go through withdrawals of seeing their face.
When you close your eyes and all you can see is someones face in your
head.
When you go through pictures of a person to keep the image of their face fresh in your mind.
Person 1: "What's up with you? You're
always looking up pictures of Victoria on
facebook.."
Person 2: "Oh. She's just putting me through some
intense imissyourface-syndrome. I'm trying to counteract it by seeing it via facebook, but it's not the same as face-to-face.."
