My mom's Facebook is all selfies with her hair done. When she came to visit, she had a bald spot and a frown.
My boss's Facebook is all smiling in the sun. When he came into the office, he looked like he'd been stuck in a sauna for a week.
My brother's Facebook is full of selfies in the gym. When I saw him at the grocery store, he was wearing a hat and eating a muffin.
