im good with openers but im not good at holding a conversation like once i run out of something to say im screwed what are some good things to talk about

your goal should not be to hold conversation, but give her something to think about and then walk away. make her want to come back to you, by doing this you are ofcoarse risking her not coming back. ive tried this one a few times in the field and it works quite well. Try to make sure you do it in an area with loud music
Me: Cheesy opener
Her: Haha
Me: I want to kiss you (say it at a volume where she doesnt really hear you)
Her: Sorry?
Me: What did you think i said?
Her: I dont know?
Me: Alright, I'm going to get myself and my friends a drink, I'll give you 10 minutes to think about it.

Walk away with a smile..

Good luck
