Hi mate,
Getting to the hook is cool. Remember to escalate (kino). Once you hook, chill the fuck out. Easier said then done, it does take practice. You basically vibe. Talk about whats on your mind...not what may impress her..just talk about what you find amusing..what you did that day etc........pretend you're talking to your mate, your sister etc..BE NORMAL..add in the odd randomness, just to spike the conversation "oh my god, you're trying to seduce me, I can tell"...Try to bounce her round the venue..suggest your thirsty, go to the bar etc do a round if you can afford it..you're not supplicating if you buy her a drink in the correct frame (we're just chilling!)

It takes practice but keep at it
