Have you ever bought unnecessary souvenirs when you were on holiday? My family and I have done just that. When we were holidaying in Japan, my dad suddenly asked me: “Do you want to buy something? If you want anything just tell me.” His question struck me as weird – Why would he want to buy me everything I wanted? I thought to myself. Anyway, I said “OK” and we ended up buying a lot of snacks and souvenirs. When we returned home we couldn’t finish the snacks. Then my dad remarked: “You bought so much and now you can’t finish it.” I replied, “But you let me buy whatever I wanted?” I ended up having to eat way too many sweets and snacks. I’ve since made up my mind never to buy more sweets, snacks and souvenirs than I need.
