The receptionist at work greeted me by name today. When I looked surprised, she explained that she had memorised the names of every single employee. That's over 300 people. I told her that this was impressive, and she dismissively stated "it's my job. If you had this job you'd have done the same thing".
Err, no. I really wouldn't have. I couldn't have. I'd be surprised if I could recognise and name 300 friends and relatives, let alone co-workers. Currently, I could name maybe a dozen people at my work.
Now that I come to think of it, it's not the most impressive task I've seen. A headmaster of a school I attended could name every child in the school — that's several hundred children, with a new lot coming in every year, and everybody changing appearance constantly as they aged.
How is this possible?
