<human>: Could you distill the essence of the text into 1-3 sentences?

There was this girl in my math class, I never really got a chance to get to know her ( She wasn't involved in any clubs or other extra curricular activities, I never got a chance during lunch and you can't get to know people that well in math) 

As luck would have it I happened to have a crush on said girl, I, being an awkward dude with no real experience in dating or flirting, have no idea what to do about this. 

So I got her number from a friend of mine and was planning on texting her seeing as summer break is now upon us and I have no other way of getting in touch with her. 

What should I say when I text her so that I don't sound like a creep? Or would it be too weird for me to even bother trying?
<bot>: I got the number of a girl that I pretty much don't know but have a crush on from a friend. What should I say when I text her? Or should I just not text her because it'd bee too weird?
