For instance, a massive pool party event or a block party with booze involved.

What am I supposed to do? Waltz over to a group of ladies try to isolate one and regale her with my banter do all the kino bullshit in broad daylight and convince her to leave their friends behind, get in an uber and travel half an hour back to my place to have sex with me?

Or would you just focus on just being friendly, approaching a few women and perhaps just aiming to get their numbers if you enjoy the conversation - and then if they really do seem keen for something more than we can go down that route.

Also do you have any advice for getting a number at a social event? I take it you want to have a good interaction and make the number seem natural, rather than approaching them with a singular goal of getting their number then running off, since then they'll be more likely to actually arrange a date.
