She is just playfully teasing. I am mexican and I like blue eyes because my Grandpa has them, but I think I am one of the rare people that just honestly adores brown eyes. Blue eyes are nice to look at but I just prefer dark eyes. XD
Wow... a blue eyed gringo :3♥ Yeah, she's flirting. Why do we love blue eyes? because everybody in Mexico has brown or green eyes. Blue eyes are sooo pretty and unusual. Also, "gringo" is good or bad, depends of the context. Mostly is used as a slang for "American". P. S. i'm mexican.
Gringo is just another way to call you white boy its not out of disrespect or affection. Same with gringa which is the same only that its for girls. Not all mexicans love blue eyes, I personally am a mexican and have green eyes but find dark brown eyes really atractive. So not all mexicans love blue eyes but the ones that do might be because its really rare in our to see someone with colored eyes since we are a mix of many diferent civilizations. Same happens with my green eyes.
Gringo is what we call people from the US...to be honest it is disrespectful word because the actual meaning of the word means "Green Go" which means whereever there is money Americans just go to make money out of them even if it means exploiting people and doing not very humane stuff without putting though on it. But she just seems to be doing it just to tease you, even though I don't really think she knows that the word is derogatory. Anyhow blue eyes are not common in latino America, so blue eyes are excotic for us when we see them. So yes she is flirting with you.
She doesn't seem to like you plus Mexican women are very warm when they talk to you I'm Mexican so I would know also "gringo" is a insult and as for blue eyes many Mexicans want ot HAVE blue eyes in other words she is kinda jealous of your blue eyes cause lighter features are HUGE for women to have and Mexican women who have blue eyes seem to like brown eyes
