Hehe,
If i think it unnecessary to spend money on dress and cosmetics i will use \"waste\". Perhaps i am wrong. I don't quite understand girls. As for boys i think it a waste of money to buy cigarrettes. Sometimes i drink a bit. So i spend some money on drinking.
Really? Either girls or boys have their own ways of spending money. If they think it a waste of money they will not do it. They spend money on it because they enjoy it very much. That's the way to use money. Make money and live happily with money.
