Re: "lol" response to cocky funny DHV
If I get a reply like that, I don't keep the convo going. I drop it for a while. Either she re-initiates later on or I just do so myself after a few days.
If you're hell-bent on replying, say something along these line:
"You're probably one of them, aren't you? =p"
Then again, you won't run into a situation like that if you've been doing everything right! Don't get me wrong, it'll happen. Just don't let it discourage you!
Always leave her better than you found her.
