When someone reads the message from their notifications, but doesn't open it. This may be due to:
1. They're busy.
2. They pretend to like you but aren't interested enough to listen to your problems.

This leads to people with people constantly checking their messages to see if that person even checked their message. The longer the message remains unchecked, the longer your anxiety grows.
Jack: So you up for me coming to your place this weekend.
Sam: Yeah, what time?
Jack: Is 5 PM good?

*Message left on unread for 10 hours*

*Jack starts checking his messages every few minutes, his faith in his so called friend dwindling every second.*
