A FB notification you don't really pay attention to when you receive it, because it's not the notification you were expecting in response to you
Zoe: Hey, I asked a question on our class Facebook group. Did you see it?

Janet: No. That was probably a gray notification for me because no one liked my new Facebook status.

Zoe: Loser.

Janet: Hey! Admit it! Everyone prefers likes on their Facebook posts!
