Death glare from beautiful woman

Anonymous
Trying to sound modest but I'm not an ugly guy or anything. I am in great shape, have muscles, but not like jersey shore steroid muscular.

So there is very beautiful girl at my gym, she is there all the time as am I, she looks like she's in her mid-20s. I won't check her out. I absolutely refuse to give her the time of day, just because she strikes me as one of those stuck up gorgeous women.

So I walk around the corner, and there she is facing me, and instantly the look on her face went from neutral to the glare of death like I wronged her in some horrible way in the 0.5 second I did look at her.

I'm interested to know the woman psychology. Does that mean she hates me because I won't EVER acknowledge her? Or did she think I was scoping her out like the rest of the guys drooling over her in that 0.5 of a second?

I'm not sure why every girl who answers this question seems to think I was checking her out or starring dead at her for. I walked around the corner she was just there as I passed her. Do girls check out each and every single guy they see? Even if they are like 500lbs and a 70inch waste line? No, you just happen to see them, even for half a second( I do not exaggerate of that time frame either)

She came up to me today! She told me she though I was really cute! I kinda just made a tiny bit of small talk and politely backed out because I'm not interested but WtF?
