Thanks for the credit. I didn't ask for it. ;-)
I think you've pretty much got it down: Be funny and engaging and original to get their attention. The only thing I worry about with you is being funny and continuing the routines in an effort to keep the ROI high. Without putting the moves into place which make a meetup possible, your work will have diminishing returns and eventually make it very difficult to close a meeting.
You need to take a few more risks and get to setting something up. I won't proclaim to be a TXT game master; I'm still learning too. But you'll probably need to do it in a way that is congruent with the level of interest you think you have. Either direct, or covert.
"Hey, you're cute, let's get together."or
"Hey, you're cute, let's get together. I'll show you why laundry is so important. I'm a clothier for orphaned street children. It's awesome and the ladies love me for it."
"I do a lot of laundry, yes. I'm not sure why. There's something about you that tells me you could help me improve my laundry process. Like you're really anal and efficient or something. Maybe you could come and watch my process, and we could exchange notes. We could produce a laundry blog."
"You're cute, but something tells me you want to mother my laundry. I've already got a mom. But I'd be open to seeing some alternative laundry tricks. Come down the next time I'm doing socks."
Obviously you'd have to shorten these up but they illustrate the point. Keep in mind that you sometimes have to cut your losses. There IS a perfect way to game every girl, but knowing what that is is nearly impossible. You may not get what you want out of every interaction, but since you have a particular interest in this part of your game, you can bet that women will remember you for your original texts.
I've had girls tell me. "Your txts are SOOO different from all the other guys out there."
