You didnt get her attention in your opener. send her something exciting or make her curious like
You: OMG security camera taped us !
or
If you got HER number but she doesnt have yours saved in her contacts then you can use something anonymous or canned like
You : Who was that cool guy you were with **** night ?
Just need to grab her attention right away then SHE will supply the material for you to go on....
for ex
You totally missed the point that she told you she still felt drunk when she woke up... so she prolly had enough to drink that she has some memory lapses about the evening, use it to accuse her of having tried to pick you up or seduce you. in a cocky funny way of course
You : wow you really get all touchy feely when you drink dont cha ?

good thing THAT didnt get taped ....
or my personal favorite
YOU: hey you said you werent gonna leave any marks
get her mind racing
the part with something in the drink is just too creepy, all girls fear this situation, accusing her of it prolly totally pissed her off.
I always Push Pull ( actually I always pull first and push second never the other way around ) within the same text.. say something super sweet or kind or compliment her ( helps if its sexy ), then stomp on it ..
like
hey i really had fun ! you were so hot in that skirt !. too bad it totally clashed with your shoes
but hey whatever suits your style I guess, I just dont think you should use canned stuff, cuz they will ALWAYS supply you with material...
