We say everything is normal. But normal itself is abnormal for someone else. Normal is an illusion.
Some people like to be normal. Others like to be different. The normal referred here is relative. Can we say a person who wakes up at 7am wakes up at the normal time? There is no normal because the normal has not yet been defined. Normal is an illusion.
We sometimes say he is just a normal guy. But there is nothing normal. Everyone views him from their different perspectives. When each one's perspective is different, normal cannot be possible. Normal is an illusion.
