Tonight, while me and my friend was texting each other to meet up a text message came from his phone 'Who is this? I had arrived where we were meeting, and I was sitting across from him now. So, we had stopped texting each other. The texting continued even after he turned his phone off. The texter said his name was the same name. The texter texting me from his phone number while he has his phone in his hand, and it was powered off. Can someone explain this?
