Is your proof the percentage that girls respond to you sending one message versus you sending a different message? You turned it into a scientific experiment, dude -- not cool. You get credit for crunching the numbers, and that's sort of interesting to see the results, but listen -- you have your 'proof,' and I have my own. If your methods work for you, awesome. But in my experience, the
majority of the time, girls are going to be creeped out by "knock knock" and they're going to be bored with "tell me something interesting about yourself!

" There's more interesting ways to ask someone to tell you something interesting. Also I don't think guys don't use smiley faces, most of my female friends think that's weird, too, they all say there's something feminine about it.
