Not only that, you don't even blink very often. You don't tell me what's going on with you, and I'm losing interest. I thought things would be different; I thought you would be vibrant and varied, willing to alert me instantly of texts, emails, and incoming calls in a rainbow of colors. There's so much to like about you, but this is really becoming a problem.
