When you're out at a club and end up talking with a girl who's quite drunk, is it better to leave it alone? The other night I was talking to an extremely interesting law student and we made a game of throwing out names of movies and shows to compare tastes (we were literally 1:1). Eventually she got touchy and stayed close to me for the rest of the night, and we kissed a lot. Eventually she took my phone and put in her number, then left due to her friend.

I texted her the day after (yesterday), but no reply since even though WhatsApp shows last time online and such. I assume it's dead in the water. How can you avoid these situations?
