Jill and her best friend do everything together. They are in the same class and ride the same bus and play at the same park, etc. I was baby sitting Mia and I thought she would be glad to see the girls. I was wrong. She kept getting mad and folding her arms and complaining to me. All she would say was, "Jill keeps taking my stuff!" You see, many of Mia's toys are inherited from her cousin who is 3 years older. Since Mia is 4, she can't remember a time when all these things were not hers. But, in truth, many of Mia's things originally belonged to Jill. What can I say? They are both right. Anyway, I said to Jill, "Be nice to Mia. She has been wanting to play with you all day." Jill looked at Mia and said, "Actually, that shirt you are wearing used to be mine."
