Man, when i first started on neg-hits, i was doing it all wrong. Instead of coming off C+F i'd just come off like a total arse and get uncertain looks...It took me a year of practice to start doing neg hit's right...the right timing, just mean enough, the right smile or frown...now i can actually see the attraction grow with each comment. The sh1te works if you do it right, no doubt.
As for hanging up on some chick you met online and talked to for a full minute, that's got absolutely nothing (as far as i can see) with being a DJ, getting to ANY LEVEL AT ALL, or coming off as Strong, Confident (other than that she won't be sleeping with you tonight) or Smooth. Kinda seems like you screwed up a bit, couldn't think of a good way to recover, and ran scared...as for calling you back over and over...is that really true?
