In this one, you have to try to find what's wrong with the following paragraph. Ready? Okay, go.

So, this kid named Jimmy lived in a one-story house with his mother, father, and sister Amanda. One day, he was bored because his father was out of town and he always did fun things with his dad.When he was sitting in his living room, he heard a knock at his front door. He went to open it but found his mom already there as his friend Kevin walked in. Kevin asked him if he could go rollerskating with him. After his mother gave him permission, he ran upstairs to his room, found his roller skates, and returned to the doorway. He and Kevin then headed off down the street.

So, what's wrong with this paragraph? You tell me.
