You avoid false validation
Everyone knows that omnipresent couple on social media... and everyone hates them. They upload incessant "usies" that all look the same, banter about last night's amazinggg dinner via Facebook comments, and post "I love you babe" on each other's walls. Yes, you're aware that this advertised version of their relationship is all smoke and mirrors, but it's hard to constantly remind yourself of that.
So you covetously look at Mitch and Deborah and think, "Wow, I want a love like theirs!" But what you DON'T know is that they had a screaming fight last night over who finished the box of Bagel Bites. You think they’d share a status update about that? Of course not! People only tell the world the good stuff because it’s a way to show off and seek validation from others.
