I have never been able to make sense of my idea    31  money. I can walk into a store and spend $ 700 on suit,   32  go home and squeeze(挤)three cups of tea out of a single teabag. Am I a spendthrift or a miser or both?

A spendthrift is a person   33   likes to spend money. He always buys things 34    regard to cost. All of his spending gives him   35   (please), so he enjoys 36.    with shopping spending. He is both warmhearted and free - handed. He has a lot of friends    37   he often treats everybody to drinks and meals. He would even give or lend money to his   38 (bad)  enemy! Some people can accept a spendthrift's habits very easily. They consider such a person inexperienced,  39they enjoy being with him.

Are you a little like the person just  40    (write) about? If you are one of the big spenders of the world, you will always have debts, but you may have a lot of fun, too.
