I had an appointment today with a new touring lady. She emailed me her phone number last night and asked me to text her for the exact location when I was in the neighborhood just before the appointed time.
So today I drove to the neighborhood and texted her. After 10 minutes of no response, I texted her again. Then I called her, but got "The number you have dialed is not in service." Then I emailed her, still no response. When I was about to give up almost 30 minutes after our original appointed time, I received a text from her (I had given her my phone number also) asking why she had not heard from me. When I saw the incoming phone number displayed, it became clear what the problem was: the phone number she emailed me last night had one wrong digit!
The lesson is: When setting up a meeting with someone new, be sure to provide correct phone numbers.
