Just to show I'm game for (almost) anything, I gave it a shot (the original task, not the dude idea), too. I just love social experiments..
Now the original message post was to text any girl in your contact list, implying that I have some discretion as to whom I harass. This is truly key to your success or failure on this mission.
So, I quickly ruled out professional contacts. I mean, if I hit on Sister Marie (75 years old), she would probably be very offended. Or worse, she might not be offended and consider it a serious offer.
I ruled out wifey. This would definitely piss her off and I didn't feel like going without sex at home for another 5 weeks . That left the harem.
#1 and #2 both were silent on the initial pitch and haven't texted back. I'm figuring they assumed the wife had gotten my phone and was baiting them. I'll have to email later, I suppose.
#3 went much better.
Me: Hey, when you gonna let me tap that again?
Me: I'm a busy man, I need an answer.
her: Tomorrow OK?
I figured I should quit while I was ahead (or at least not too far behind) so that was the last message sent.
Kids, do not try this at home.
