A handwritten note from Britain's Prince Charles is being put up for sale in the US.
In the letter - written to Janet Jenkins, a receptionist at the British consulate in Montreal, Canada, in June 1980 - the Prince revealed his concerns about starting a family, having children and getting divorced, something he later did with Princess Diana.
The letter reads: "I do hope you have recovered from the traumatic business of marriage and divorce in such a short time.
"Thank goodness you discovered the mistake early enough and didn't start a family.
"Starting a family and making a mistake like that is frankly, something which concerns me enormously."
In the letter - which is one of six he sent to Ms Jenkins - the Prince also dwelt on the pressures he faced as the future King and the interest surrounding his own love life.
He added: "I shall just have to get married as soon as possible and then all these people might relax a little! I still think my solution of marrying a girl from each Commonwealth country is the best one."
