I had one of those "excellent investment" calls today. You probably know the routine. An excited young man calls you at home unsolicited and totally out of the blue to offer you the opportunity to make well above average returns for your money. Of course it will involve investing about £10,000 and you have to make a decision soon or you'll lose the opportunity. This time the marvellous opportunity was in real estate in Natal in Brazil. I won't bore you with the detail, but his arguments soon started to fall apart when I probed a bit.
Sadly for him I wasn't busy at the time. I kept him talking for an hour before he realised he was going to get nowhere. By the time the call ended he realised my scheme for investing in Natural Colour Diamonds would be far more profitable for his money.
ps I wonder why women never make these calls.
