I am always fashionably late...
As to the pretty/attractive subject, if you get slew of the sexually toned gazes from the guys, get approached when at the club with multitude of short stupid yet somewhat empowering statements about being attractive to their T driven desires, or see the grown man behave like little boys trying to master enough courage to approach you and say some of the lines I have mentioned before....You probably are pretty.
Now, if you work with multitude of people and female customers do tell you how pretty you are, then even more so, you are probably very pretty.
And even then, even though the feeling is extremely pleasant and reassuring, even then, you your self do find what is wrong with your look, and you keep on looking for improvements.
I know of some famous models, whose success had proven that they should believe without a single doubt that they are in fact gorgeous, yet reality proves otherwise and leaves them wondering just the same.
I guess, the uncertainty is just a part of being a real woman.....
