I met this girl who is really bad with texting/calling. Before everyone jumps on the "she's just not into you" train, she's not just bad with me, but everyone. We have mutual friends (girls, her sister) who are always frustrated with her lack of response over the phone.

We always have a great time when we're out together with friends, and I've been able to connect with her really well. I've tried to make plans for a date with her while we're out, but it has been difficult following up. Any advice on how I can set up a date with minimal phone usage?
