When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity.
The profound nature of relativity is not merely an abstraction of physics, it also explains why the distance from 1 to 1 million is greater than from 3 million to 5 million.
Each of us is incomplete compared to someone else -- an animal's incomplete compared to a person... and a person compared to God, who is complete only to be imaginary.
