No, actually he is correct

The 5th time the boys came out of their room tonight they were instructed that I wanted them to stay in bed and I'd see them again tomorrow.

10 minutes later...

Jack sheepishly comes out of his room and looks in the computer room, where I was working.

"Mom."

"Yes Jack."

"Ty is saying something wrong."
Jack is obviously looking for either an excuse to get out of bed or an opportunity to get his brother in trouble.

[Ty appears with a grin on his face.]

"What did Ty say?"

"He said I was in trouble."

"You're not, but you will be if you come out here again."

Ty: "But he he he he bite my finger."

[holds up finger]

Me: "Jack did you bite Ty's finger?"

Jack: "Uh-huh."

Me: "Well then Ty's right, you are in trouble."
