That sentence contains at least five follow-up questions she WANTS you to ask. Where in Florida? What brought you here? How long have you been in the area? What do you miss? How does it compare to here?
She handed them to you on a silver platter. And you said, "Oh cool. I come here every week. I love this band. Ummm... pretty crowded tonight."
She smiled politely. Nodded. And never texted you back.
I was that guy for years. Talking too much. Listening too little. Panicking about my next sentence while she was literally feeding me the answers.
Then I found 22 rules that fixed the whole thing. Rule number one: shut up and listen. She'll tell you exactly what to say.
You asked her if she wanted to grab coffee. Then you asked if the time worked. Then you asked if the place was okay. Then you asked if she'd prefer tea.
Four questions. Four chances for her to say no. Four signals that you're terrified of making a decision.
Plan it. Pick the place. Pick the time. Tell her where to meet you. She'll either show up or she won't.
Either way, you look like a man instead of a scared little boy.
You texted a girl on Sunday night to confirm a date with you on Friday night because she flirted with you a little? Come on bro, it's like you got NOTHING to do except date her.
Yes, it's common courtesy to respond. You did try to confirm too far ahead of time, but not responding is disrespectful. If she never gets back to you then I would suggest not going. No need to let her know you're not going either, if she can't get back to you then it's none of her concern. If this happens and she complains you didn't pick her up, tough sh*t. "Oh shoot, you never got back to me so I didn't think you were in. I made other plans"
