Number-closed 5 people in Athens. One thing that I learned is that make sure that you take her phone and number-close (or IG or FB). Just say yours has a problem with the touch display if she hesitates.

Just comes off much better and it is as if she is number-closing you.

Another reason is that you make sure that she doesnt ghost your request after you have talked. You are in the control of accepting her request instead of the other Way around.
