I don't have to hang out with you just because you're Black or whatever else. I met this guy a while back and every-time he would introduce himself to people he would say "I'm from India". Like am I supposed to feel sorry for this guy and give him my house now? That's the tone he would say it in, like people owed him something.
Maybe say something like: "Hi I'm an Electrical Engineer with a Master's in Physics, also check out this super-computer I built myself."
