How do I know if I am ugly to most people?

How do I know if I am ugly to most people? One of the most important question i have made in Qoura  ;))
There are some near-definitive indicators:

• Babies burst into tears on sight of you.
• Older children run to hide behind their parents.
• Adults avert their eyes from your countenance.
• Dogs bark at you in the street and less assertive animals flee.
• You can answer yes to the question "Has a torch-bearing mob ever tried to drive you out of the village?".
• You find that Greek men will only look at you indirectly, for example using a mirror.

Such 'quirks' make a person's appearance unique and 'unique' is for me, attractive or beautiful or whatever you want to call the opposite of ugly.

Also: to use an analogy, you can admire a stained glass window, even an 'ugly' one,  but it is only when you see sunlight streaming through it that its beauty is revealed.

I have met people with what many (not all -  I know!) would consider 'defects': large port wine stains [3], scars and so on and - after the initial visual registration of course - completely disregarded those features given how nice/kind/funny/sexy/smar
