"I get pocket money every week if I'm good and I also earn money. I used to spend all my money at once but after Christmas I made a huge mistake. I bought something and then played with it and then realised I didn't want it. We had already opened it so we couldn't give it back and then we had to sell it for less than we got it. So now I am way more careful with my money. I do use my money to buy other people things or presents a lot of the time though!!"
