FYI I did use the correct number close.. At the time for number i genuine believed i had attraction i wasn't even "assuming" it; I believed; I even qualified her ;
We spoke out families, school, interestes, etc; very natural convo
I didn't "ask for her number"...
I whipped out my phone said her name and said "what is your number"; a demand not a question with full confidence..
So In retrospect I probably should have spoken to her longer and developed more comfort;
But she was def a "hired gun"
