I go for a walk and look at the beautiful landscape. I rest on a bench and relax my feet. I let my shoe dangle. I'll go on later. Suddenly I get stuck with my heel. The Heel is very stuck. I can't get the shoe out and have to pull the shoe very hard. Suddenly the Heel break off. Oh no, my shoe is totally destroyed. I keep walking with a broken shoe. It is not convenient. I throw the shoe away and go on with just one shoe.
