<human>: I am a 20 something male, she is a 20 something female.

I am interested in dating this girl, but am wondering if we're off to a good start.

First time we talked (last week), she seemed pretty cool and normal, no signs of interest except a generally friendly disposition. Talked about college/random stuff. My first impression of her is that she comes off as an introverted but adorable type of girl.

Decided to be a champ and blatantly asked her number after the long labor day weekend. 

Me: "Hey, so Derpette, can I have your number?"

She gets absolutely flustered

Derpette: "Oh wow, that's forward!" 

Mentions how she needs to do a "background check", starts playing around with random things in the table, mentions how she's serious about the "background check" (but not really, she seemed just lost for words), she avoids eye contact, her face turns red, i'm not sure if she was smiling or her facial muscles just couldn't muster up a response.

I keep quiet and watch her because it was nothing like i've ever seen before. She eventually gives the number, but not without me asking again playfully.

The rest of the day, she seemed back to normal. Was her reaction normal? Can there be anything analyzed from it? I have never encountered such a strange reaction. Usually, they go "sure!", and give their numbers.

Can you condense the text into three sentences or less?
<bot>: Encountered unsuspecting derpette I like, asked her number blatantly, she exhibits chipmunk like behavior, what do?
