If she says, “Yeah, that sounds fun!” you can say, “Okay, awesome!” Then pull out your phone, bring it to the “add contact” screen, hand it to her, and tell her to put her number into your phone. If she says something along the lines of “No” followed by an excuse (like “I have a boyfriend”), you can say, “No worries, just take it as a compliment then,” and leave the conversation.
