I was once talking to a colleague who was showing me some old vacation pictures. Some tropical area. I commented that they were looking amazing. He said that actually there was a pile of garbage next to them, but they only put the good looking photos on Facebook.
Everybody wants to look perfect online, so much of the appearances are faked. It makes sense, since everything is public, so we feel pressured to make ourselves look good. Repeated, I am not surprised that it can cause harmful psychological effects.
