This is an update to one of my other posts about this girl I go to youth group with and also who I chat with the next day in the library.

So after a few weeks of deciding weather if I want to ask this girl N out I finally decide what the hell whats the worse that could happen. So since she always in the library on wednesdays I decide I would ask her if she wanted to grab some food from this cool indian restaurant nearby. 

Thing is she wasnt here today and its finals week so I might not see her for a while so I shoot her this message. 

"Hey N are you doing anything this weeked?"

She responds with working and thats about it why?

I say "I was going to check out this indian restaurant up here and was wondering if you wanted to tag along thats all" this was sent at 1:21

at 2:47 so a couple hours later me thinkin she probably doesnt want to she finally responds with "I could bring a few friends sounds fun... what time?" 

The friends thing threw me off but I would rather hang out with her than nothing so I say sure.

QUESTION: Is this a bad sign that she didnt like me like that or is she shy or what? Advice and personal opinions appreciated

Can you provide a brief overview of the text?
<bot>: Asked girl out dont get a response for a few hours, finally get one and she says sure she bring friends? Good or bad? Time to walk?
