How to respond to "it's possible" after date invite?
Backstory: Met this girl and her friend at a bar in my local area. They came up to me so that should show some interest already. They thought I looked like ed sheeran, so we got a couple pictures together and exchanged a few words. Then parted ways, which I kicked myself for, so I waited until close for them to walk by, and when I was about to walk out the door the girl says goodbye, so I took that opportunity to turn around and tell her it doesn't need to be the last time we see each other and that we should hangout. She says definitely and seems interested. Grabbed her number and left. Pictures show following conversation. This point in the conversation seems like one of those where depending on what I say it could set up the date or it could fuck up the whole thing. Some possible responses I've thought of: 1.) "You don't sound confident" 2.) "Possible?" 3.) Getting her on a phone call to connect with and set up logistics 4.) Or just take "it's possible" at face value and say "Good, how does next Saturday around 9pm sound"
