A woman where I worked many years ago did Star Charts as a hobby. We'd only really met a couple of times at the coffee machine. DD2 had an approaching birthday so I asked her to do a chart as a present. She needed the date, time and place of birth. She was perplexed with the result saying it came out complete unlike the daughter we'd talked about (at the coffee machine, shared interest in horses I think) and very relieved on discovering the daughter she knew about (DD1 - Scorpio - outdoor horse lover) was not the one she done the chart for and didn't know existed (DD2 - Virgo - indoor arty type). And the chart was spot on!
She then did charts for my other two children, who she'd never met, and they were spot on too. I declined allowing her to do mine. Too spooky. Too much information!
