Ann: 2018 AGM Presentation, page-47

i don't need to "believe". I "look" at the share price over the last 12 months and have genuine concerns with an investment in a company that has constantly and consistently disappointed the market. Concerns I've followed through on by selling half my holdings over the last month. If you bought them I hope they go well. 

Meanwhile enjoy your meals with directors, and your first class tickets to mars with Elon and Branson and all the other imaginary beliefs you have in your Walter Mitty world.
