Message: Do you ever trade things with your friends? When I was growing up we used to trade stuff all the time, trying to get something we thought was better than what we had. We would trade baseball, football, and basketball cards with each other during the seasons for those sports. We would trade desserts at lunch time at school. Sometimes we would even trade some toys we were tired of for something that our friends were also willing to trade. The key in good trading is to get something you want, or something that seems to be worth more than what you have.
