weekend up at balmoral castle. and i guessed, i said, was it prince andrew? she said, no, actually it was with prince charles. >> prince charles, the country's most eligible bachelor. diana once anonymous is now famous. >> i think it was over whelming, but she was still trying to come to work because she couldn't spend her life cooped up in her apartment. >> she was good humor. sometimes she stopped for a chat. >> but she never stops for an interview or poses for a photograph. that is, until late september 1980, at this london kindergarten where diana works part time. >> she came out with two of the children from the nursery. halfway through taking the picture, the sun came out. and we saw that beautiful lace.
