I was at a car boot sale (mix between a flea market and yard sale for the Americans out there) the stall next to me was selling a PC tower, monitor, keyboard and mouse for £10. So all day I was trying to sell my old toys (I was 9 at the time) but only made £5.

At the end of the day I went to the stall and asked if he would take £5 for it, he then game me it for free as he saw me trying to sell my toys all day.
