NEWSFLASH: How NOT to get a Girl's Number

So, I'm sitting in Sbisa eating my typical Tuesday lunch in between classes, while studying for a quiz. There are PLENTY of seats available, and yet these two foreign guys come and sit down right next to me. The conversation goes a bit like that

Foreign Guy 1: Hi, I'm alsdkfjaoisfjsd!
Me: I'm Kylie, nice to meet you.
Foreign Guy 2: I'm aslduoweifjskafjwoei
Me: Nice to meet you
Foreign Guy 1 & 2: *Talks about math concepts that are WAY over my head.*
Foreign Guy 1: What do you think about this concept?
Me: I lost y'all about 10 minutes ago. I'm not a math person.
Foreign Guy 2: What major are you that doesn't involve a lot of math?
Me: I'm an education major.
Foreign Guy 1 & 2: *laughs for a long time*
Foreign Guy 2: Only people who can't keep up in engineering become teachers!
Me: Nah, I love my major!
Foreign Guy 1 & 2: *Resume geek speak. 10 minutes later they proceed to pack up their belongings*
Foreign Guy 1: Well it was nice eating with you, can I have your number so I can tutor you in your math classes?
Me: I don't have any more math classes to take, but thank you!
Foreign Guy 2: Well, can I have it anyway?
Me: No?
Foreign Guy 1: Why not? That's rude!
Me: Typically girls don't give you their number after you insult them and laugh at them...
Foreign Guy 2: Oh. Well. Bye then.
