<human>: So I go to a engineering/math based school, which means the population of students is mostly 1) asian 2) male and 3) nerdy. The fact that I'm in the math program amplifies it even more. 

I find this awesome! The only problem is that no one ever talks to or sits beside me! The lecture room will be absolutely full, but the two seats on either side of me will be empty (No, I don't smell bad!). I'm white, a female, and I don't look like the nerdiest person in the world. 

I've talked to my friends about this and they say that I just seem intimidating before you get to know me. A few of guys said they felt as if they weren't "worthy" of talking to me, because I seemed like I wouldn't give someone like them the time of day. THIS IS LITERALLY WHAT THEY SAID. And I don't know why people feel that way! I don't have a bitchy resting face-- I'm always smiling. So if the social people I know felt this way, I can see why none of the shy ones in my program talk to me.

How do I make myself seem more approachable?

Can you provide a brief overview of the text?
<bot>: People never talk to me because apparantly I seem like I wouldn't give them the time of day. How do I change the vibe that I **accidentally** give off?
