Re: Any ideas on how to open (via text) someone you haven't seen in a month
At the moment, considering that you got her number from her sister and it's been a month, she probably does not remember who you even are. Thus, you are basically starting from ground zero, with a text opener, and with virtually no contact in her memory. Things are pretty much near a definite conclusion of failure.
I said near though. You can never leave out the possibility that things MIGHT work. After all, I never got my last girlfriend's number directly from her anyways, and I had never met her before that. Thus, I think it's still possible. It's a matter of playing your cards right.
I would recommend to begin on the topic of getting her to remember who you are. Play the typical "Guess Who" game, and really begin to get the ball rolling in the interaction.
