Observation

I was with a cute college chick at a bar not too long ago, and saw her turn on her phone. Her text notification icon said '6'. When she clicked it, she had a list of 6 'new messages', but some of the times are old. She looked through it trying to decide which to respond to. She chose one out of the six to reply to then put her phone away. As she was putting it away, I saw her phone was in silent mode.

Discussion

Every attractive girl I've seen texting has had her phone on silent and a list of unclicked texts. For this reason alone, calling is almost pointless as she will not hear it ring and how many girls other than your girlfriend actually call back instead of a text?

Attractive women treat their text message inboxes like many people treat their email inboxes, even though they dont want to read one, they dont click on it nor delete it and let the junk accumulate. This makes them lose track of several of them over time and dont feel the need to reply because they forgot what was the last notfication number. In addition, there's no sense of urgency because a notification number changing from 6 to 7 is not the same as 0 to 1.

My theory is that if they left their ringer on, it would be pointless because women have so many app notifications and texts coming in it would be annoying and nothing would stand out.

Conclusion

Even if you had good rapport during your interaction at the time you got her number you'll often be lost in a sea of texts and are easily forgotten based on her organization and volume settings alone. Your timing has to be exact and cannot be predicted, especially when her friends' texts come in at the same time (they have first priority).

Always talk to several women simultaneously to mitigate the flaking. In a pool of 3-5, one should be down for at least a meetup. Always be looking for new prospects. This is the flaking generation.
