Nobody is perfect
There is no such thing as perfect
Not even in concept
Theory
Some people hide their flaws
Successfully
And some flaws are so common "most people" don't consider them flaws
Off leash dogs
Jaywalking
Phone addiction
Talk too much and too loudly
Homophobia
Materialistic
Lazy
Superficial
But some people have more flaws than others
Some people are not aware of their flaws
People change over time
If it looks too good to be true, it often is
Example. Mister redelings
