On Tuesday Aria tells Bu, a workmate, that she is: ‘thinking of selling her car which is worth about £2,000’. On Wednesday morning Bu emails Aria: ‘Will take the car for £2,000, will pay U when I see U’. Aria replies by email on Wednesday evening: ‘Don’t be silly, I was not actually offering to sell the car but, having thought about it, you can have it for £2,500. I know you will want it so don’t bother writing back unless you are not interested.’ Bu is so annoyed when he reads the first sentence of Aria’s email that he immediately deletes it. On Saturday Aria drives round to Bu’s house to deliver the car and demands payment. Discuss.
Would your answer differ if, after reading all of the email Aria sent on Wednesday evening, Bu decided he wanted to buy the car for £2,500 and Aria now refuses to deliver it?
