So he saw a big basket of some very red, long fruit, the cheapest in the shop. He bought a whole kilogram of the fruit and started 32 it. But after he ate some of it, his eyes and mouth 33 and burned, and his face became red. He coughed and choked, jumping up and down. 　　But he still continued to eat the fruit!

But the stupid said, "No, I can’t stop! I 37 money for them, and now I’ll eat them. It’s my money!" 　　And you think that was stupid, right 38, we sometimes do a lot of things like that. We invest money, time or effort in a relationship, business or job. Even though bitter experience tells us it won’t work, we still continue just 39 we’ve invested money, time, effort and love into it. Just like the man who ate the peppers and 40 so much but couldn’t stop because he didn’t want to waste the money he’d paid.
