Everybody is appearing with a mask which is smiling, happy-looking, so everybody is deceiving  everybody else. You also appear with a  mask, so others think  you are happier: you think other are happier. The grass looks greener on the other side of the fence: but from both the sides. The people who  are living on the other side of the fence….. They see your grass and it looks greener. It really looks greener, thicker, better. That is the  illusion that distance creates.
