Who are you

Virtually everybody has bluetooth enabled mobile phones and I suffer greatly with name recall. This app scans the content of any nearby phone and immediately gives me a full synopsis of people in my vicinity. The app would interrogate the phone for relationships, names and ages of spouse and children, where they last went on holiday, shoe size, and other comletely superfluous information. A quick glance at my phone would then allow me to say with some confidence "Hello Mark, nice to see you again. How's Mary, is she alright now, it must have been awful seeing her suffering from depression for so long. And the kids, Jack and Jill isn't it, gosh, Jack must be 14 now, all grown up hey. How was Barbados, you stayed at Accra Beach didn't you. Never been there myself but I've heard it's fabulous. Congrats on the promotion by the way." I come away looking like a normal human being and Mark can spend the next two days saying to himself "Who the f... was that?" - payback!
