1) My friend Sam asks me to look after his pet cat while he is holiday and in return I don't have to pay him back that £15 I owe him from last week. I say 'I'd love to. No problem.' On the day that Sam is supposed to go on holiday, I decide I have too much on my plate, and tell Sam that I will no longer look after the cat.
