Two scenarios - You tested positive for COVID. So you go visit someone you dislike, you made sure you coughed. A few weeks later, you find out they caught covid, and died from it. How would you feel? Second one - Your friend is going on holiday, they're in a rush and give you some money to get a lottery ticket, a lucky dip of random numbers. Before leaving the store, you buy one too for yourself. The draw is on tonight, and you win the jackpot, but you know fine well it was the first ticket you bought, your friends, that won. What do you do?
