Why do people think they look ugly?

Why do some people think they look ugly?
Most people look: normal, fine, average, etc. and they still call them themselves--UGLY. I wonder...
According to most people, some just want attention by saying they are ugly and have someone say they are not.

I admit, I say things like this too.

Wishing.

Sometimes I wonder if my wishes would come true.
The problem is, I have too many.

If all of them would come true, I would be quite happy. But none the less, I will probably regret making some of my wishes. And if they were to come true, I'll start wishing they did not in the first place.

I like to make wishes.
One that probably won't come true.
